    I recently purchased a couple WM8650 devices.
    They're not bad netbooks, but they have an really poor operating system (Windows CE7) and the wireless doesn't function correctly.

    If there was a Linux distro for these things (other then Android), they could actually be pretty cool.

    And the price is only slightly higher then the RaspberryPi

    @Jim,

    Try looking here:

    http://devio.us/~nextvolume/via_arm/viewforum.php?id=4

    and here

    http://www.slatedroid.com/topic/21211-7-wm8650-netbook-linux-port/

    plus there are probably more links on those pages that might be helpful.

    Good luck finding a Linux distro that works on those netbooks for you and also gets your wireless working.

    You get what you pay for.

    If you all you care about is getting the (seemingly) best hardware specifications for a certain dollar amount, I am sure it is a great choice. If, however, you care about software and end user support, you might want to buy something else which may have a slightly dated processor but is supplied by a company that is known to continously invest in software development.

    Well, those are a start.
    Looks like Angstrom Linux has been ported, but Debian is still a work in progress.
    Hopefully, in the future these netbooks will be usable.

    When tablets first appeared they shipped pretty much anything that they could get to boot (I've seen some - I'm not joking!).

    That includes things like the WM8650, that chip is 2 generations behind the Raspberry Pi. Most of the low end has now been taken over by the Allwinner A10, it's got a Cortex A8 and a Mali-400 GPU. It's just ahead of the first iPad CPU wise but surprisingly good given the price they go for (do a search on eBay). There's a whole bunch of companies targeting this end of the market so expect to get even more for your (little) money soon.

    Thanks for pointing that out Andreas.
    I have a message sent to the guy that probably made that possible, but he hasn't responded yet.

    Debian on a WM8650 based device is probably pretty slow, but it should be a big improvement over Win CE.

    Edit - Now that i think about it, the "you get what you pay for" line makes even less sense.
    I paid $19 for my Quicksilver and $75 for my 1.42 GHz FW800. Both were worth more in my opinion.
    If you search around, sometimes you get a lot more then you paid for.

    My FW800 is still faster (by a little).
    I guess they're creeping up there slowly.
    If its cheap it might be useful, since Freescale processors that are more powerful then this usually command a high price.

    Not so bad being wrong. eh Andreas?

    And probably even more so when you not only take the clock frequencies into account but also the performances per clock.

    > I guess they're creeping up there slowly.

    Yes, apparently they're slowly creeping up to their previously announced 1.5 GHz the same way Freescale is slowly creeping up to their originally announced 2.5 GHz (currently at 2.4 GHz) :-)

    > If its cheap it might be useful

    Surprisingly, Avnet is already listing the Black Mamba chips (albeit only up to 1.2 GHz for now):

    1.2 GHz APM86691: 73...80 USD
    1.2 GHz APM86692: 110...120 USD

    The statement was made in reference to the purchase of brand new electronics products. Pointing out exceptions such as second-hand sales between individuals or special discounts after a product has reached the end of its life does little to disprove the rule.

    I am certain it is fair to say that the majority of visitors of this website value quality software much more than raw processing power or hardware feature lists. Since you are a frequent poster, it is surprising to me that you consider Cortex A8-based ARM hardware options to be too slow, yet you buy even slower hardware from manufacturers who spend very few resources on software development and testing and represent opposite values regarding the priority of software and hardware when you compare them with MorphOS.

    I suppose the mystery of consumer behaviour continues...

    I am familiar with the Allwinner A10. I did not mean to say that you cannot get reasonably good processing power at bargain prices. I was trying to point out that by going for the very lowest prices you end up buying from manufacturers that deliberately do not spend much on the software side which has strong implications for the overall consumer experience.

    I have seen quite a few entry-level tablets with horrible Android ports that were good at little else but giving Android a bad name.

    Yes, I do have a different priority with this low end hardware then I do with better/more expensive hardware.
    And I would never recommend an ARM11 solution to anyone else.
    I just wanted a compact system with a tolerable browser (which, btw, this system does NOT have without Debian).
    The only reason I'm not in favor of A8 devices is that A9 is available at a comparable price (while A15 is likely to be slightly more expensive).
    AND, I'd prefer a PPC solution.

    I greatly appreciate the functionality of MorphOS "out of the box".
    Frankly, if I couldn't have modded this device, I would have gotten rid of it.

    That was sort of my point. There are some really abysmal tablets out there but newer versions of Android and newer chips seem to be rapidly changing that.

    I guess if you make complete tat it'll only ever have a very limited market and it'll dry up very quickly.

    The Chinese seem to start with making rubbish and then get better rapidly. Some of the stuff they make is easily as good as anything made in the west and usually far cheaper. This hasn't happened with tablets - yet.

    "A vague "snapshot" of the Yukon architecture for the system shows a core application architecture featuring six to eight 2Ghz ARM/x86 cores, with two additional ARM/x86 cores powering the system OS and three PowerPC cores handling backward-compatibility functions."

    I like what's also written in the article:

    "The architecture will sport ARM, Power and accelerator cores [...]. [...] Freescale aims to differentiate itself by offering a menu of both general purpose ARM and Power cores along with a new set of packet-processing accelerators [...]. [...] The company must create a software environment that straddles both the big endian Power and little endian ARM architectures. [...] ARM will not replace Power cores for Freescale, at least in the foreseeable future. The company said it has long-term plans to continue designing and supporting Power cores. [...] Power-based chips will provide higher-end performance than the ARM cores are likely to reach in the near term [...]. “You will see the Power architecture for a long time--it will co-exist for a decade-plus,” he said. The company has made no change in the resources it puts behind Power cores, and “we are still going to refine existing Power cores [because] we see Power has a strong base in this sector,” he added. [...] In the short term, Freescale has a deep and broad investment in Power."

    And from the Freescale press release:

    "The Layerscape architecture is the foundation of a broad array of forthcoming QorIQ multicore processors, [...] leveraging Power Architecture and ARM technologies as appropriate. [...] Future QorIQ processors based on the Layerscape architecture will leverage Power Architecture technology. Freescale continues to enhance and invest in its industry-leading Power Architecture e6500 core, which will be among the highest-performance cores featured in the new portfolio."
    http://media.freescale.com/phoenix.zhtml?c=196520&p=irol-newsArticle&ID=1706486

    And from the FTF interview:

    "Power Architecture continues to be a very significant aspect of our IP, of our offering [...]."
    http://www.youtube.com/watch?v=HD8FYGIZ2Nw

    So regarding the QorIQ product line, Power Architecture stays in and will be further developed, and ARM will be added. Nice :-)

    I bet this is something that some people thought would never happen; ARM breaking into PPC stronghold. Personally, I was sure it would happen sooner or later, but didn't think it would happen this soon, my guess was that it would have to take some ARMv8 CPU's for them to do this, but it seems they are going for the *low-end* now already (undoubtly to be followed by high end with the new generations of ARM CPU's to come). PPC is dead for the desktop market since 2007, and now a process has started to corner it in its new domains. ARM won't reach the high-end segments in these markets until the next generation of CPU's of course, but I am convinced this marks the beginning of a new way of reasoning over at Freescale, the start of a process towards a new era. Freescale isn't immune to costs, and why keep developing two architectures, costing twice as much, if you could manage all your needs with just one?

    They cant drop Power because customers depend on it. They cant switch to another platform in short term.

    The networking/communications domain is far from a "new domain" for PPC. It's been going strong in that domain since the mid-1990s:

    http://en.wikipedia.org/wiki/PowerQUICC#PowerQUICC_I (1995)
    http://en.wikipedia.org/wiki/PowerPC_400#PowerPC_403 (1994)

    The PPC had its debut in the desktop computing domain in March 1994, so it started at about the same time in both domains.

    Because Freescale's need is to get money from its customers in exchange for products, and (some?, most? of) its networking/communications customers' current and foreseeable-future need is being offered (existing and new/better/faster) Power Architecture products for several technical reasons (see also what itix said).

    Cortex-A15 is due this year...

    PPC did have its own high-end embedded niche but A8 and A9 have now got a big chunk of that level of performance. A15 looks like it'll finish the job.
    Freescale in particular pretty much owned automotive and had a big chunk of networking but a lot of the ARM guys are chasing these now.

    It's nothing new. They did have several different ISAs (ARM, Coldfire, 68K, PPC, 8-bit) until fairly recently but they have been replacing their designs with ARM based designs for some time now.

    It's got to the point where there's really no advantage in designing your own CPU any more unless it's something really exotic or special (like console CPUs). It's far easier and cheaper just to license a design. That way you get a chip that you can still tweak but you don't have to worry about developing a compiler or apps or whatever.

    Yes, huge advantages on the SW side, which of course is essential. But even if you license an ARM design (and other on-chip controllers) you can very much design your own CPU (as in "chip") around those, to target different markets and applications. IMHO there are only benefits in this, and that's why it will happen. PPC is now *deader* than dead, but it might just not know it yet...

    According to the Applied Micro CEO, not only have they created their X-Gene core from the ARMv8 ISA spec but they also helped ARM Ltd. to outline this spec to begin with:

    "When we did the deal with ARM, we licensed the micro architecture. We did not get ARM’s cores... we got 300 pieces of paper, out of which half were blank, which we helped fill up and thus got a discount (laughs)."
