You should really remember what people (you) are doing with computers these days....

Aslong as you don't plan to play any current game of run scientific SW even the smallest netbook will be plenty fast.

A MacMini1.5, PowerBook1.67 or even a PowerMac at 1.8 or more GHz is atleast as fast as such a netbook and we don't even have gone into the lands of the G5.

I'm quite certain that my iMac will carry me to several more years of MorphOS-use without problerm (assuming it ever gets officiall supported and doesn't break offcourse).

ARM might be nice for the ultra-portable niche (as in Genesi's smartbook) but if someone would get into doing an ADB-driver we might get that area to in the form of the 12" iBook.

Lets face it lack of fast-enough-HW has never been a main problem for MorphOS, not even in the times of the Peg1.....
