- Minor MOS updates (bugfixes) should be free. - Its okay to charge money for major MOS updates.
Regarding the prices, lets compare some examples: - Xandros standard costs $39 - Suse personal costs Euro 29 - Mac OS Panther costs $129
Maybe a price between 30 - 70 Euro for MOS 1.5 would be reasonable. How about offering MOS 1.5 as download version without support?
To be honest I don't like the idea to donate money per paypal to much. I would prefer to pay for product and to get a bill. (As the bill can be used to reduce my tax.)
The most wanted features of MOS 1.5 on my opinion are - DefIcons - the ambient improvements (like text view)
