VPC for pc's is free from MS now. The PPC version isn't going anywhere since Apple went to Intel and you can dual-boot.
VPC is still very important on pc's. MS doesn't have the source code for a lot of things or the license if they do. One day we won't have anything but 64-bit hardware that may not handle 32/16/8 bit code correctly. Linux can be recompiled to insure 64-bit compatability, but Windows and third-party software for it may not.
Just like Steve dumped support for OS >9 and gave away the "Classic" emulation, MS isn't going to guaranty anything but the free use of an emulator, which isn't really free, since you'll now need an extra license for the Windows you install on VPC too. :fu:
