It depends on the workload, of course. Anything that does SIMD like matrix multiplications in multimedia or scientific computing will, of course, profit from enabling AltiVec. No one claimed that AltiVec, MMX or SSE will just improve everything. > We and the MintPPC team had some problems with the VLC media player on our > Non-AltiVec > machines a year ago because it is only available in an AltiVec version. > The MintPPC team had to recompile it.

[2] I would argue that there are far more users with PowerMacs which all support AltiVecs than with obscure embedded machines. As I said, some packages like nss2 already enabled AltiVec by default.
