1) PPC is dead, dead, dead.
It's not really dead, it's used in the big three consoles of the current generation. This does mean though that IBM won't come knocking anytime soon and are unlikely to answer our phone calls.
All the pr problems they had could be fixed by shutting up and getting product out the door.
They annoyed some very vocal people at the beginning and it snowballed from there. They should keep quiet and not get involved in petty squabbles, but we should judge them on the product they sell & not their personality.
The C64X and Amiga Mini case look quite nice, I've not bought either and I'd want to know I wasn't going to get any heat problems etc before I would. The price would need to move a little as well.
