Yea, Hardware situation sucks big time!
The hardware situation has never been better - Efika, Mac Mini, Pegasos II, cheap 2nd hand PPC Macs on eBay by the bucketload thanks to Apple going Intel.
Cheap, powerful hardware capable of running OS4 is abundant - it's the licensing situation that people ought to be complaining about.
Now that they've made this update it makes me think that maybe there is some kind of plan to have future hardware besides the A1 to run OS4 on.
We can only hope so! OS4 is looking better all the time. It would be madness to put all of this work and effort in and then see it come to nothing.
