Your claim that I quoted and thus referred to was about hardware bugs in particular.

After how many years of usage? How does x86 hardware compare after same time of usage?

> Pegasos I was ruined by a bad chipset

The chipset bugs were remedied by the April2 chip, which, while slightly lowering performance, means that the bugs were not exposed.

The low amount of RAM on the Efika 5200B is not a bug.

...is not part of "that stuff" that I mentioned, for a reason.

Not a bug either.

Again, no hardware bugs.

Prices are not bugs.

> All in all just a mess really.

And virtually nothing of this mess has been caused by hardware bugs, at least when applying the generally accepted meaning of the term.
