Get real. You thought there is ever going to be a processor or computer
generation without an expiration date?
I just tried running the Reaktor demo on my ibook G3 but got an error message that altivec is needed, so it would not run at all. Altivec came with the G4 and I think its included in the G5 in some way. If Apple had somehow been able to get the G5's up to 3ghz has Jobs promised a year ago, and then move to a G6, then we could pretty well assume that future OS updates and software will continue to work with our G5's for a few years. However, in a year from now, when Mactels come out, our days are numbered, so we will have to unload the G5's at a big loss, and buy new machines. Of course, I do not blame apple, since they were dependent on IBM and these are business decisions. But it will indeed cost us if we want to keep on the cutting edge.
