Is OS4 PPC-only?
Yes
Are those of us using UAE stopped at 3.9 until we can afford the PPC machine?
Yes, although certain bits and pieces may become available for UAE (the TCP/IP stack, for example).
Just curious, because I remember Apple's transitional OS's supported both PPC and 68040 for at least 2 or 3 releases before going PPC only.
At the time PPC wasn't that much better than 68k in speed terms so a smooth transition made sense. These days we are in desperate need of better HW and companies like Eyetech need to make some money, so it makes sense to make people upgrade.
