Of the reviews that I have read from Zdnet, Macworld, etc. It seems like performance drops on PPC application running on intel are most notable when doing comparisons with the with the latest Power PC equipped macs. So most people who just bought a new machine are not going to get a new one to replace it soon after buying it and should not if they need maximum PPC performance. So you might experience a good performance gain on a PPC application running on an intel mac if you are upgrading from say a 400 Mhz G4 system or any 4-5 year old or older system. But as always buy the machine that meets you current needs as of now.. For example if you need PPC optimization now and can't wait for intel optimization get a PPC mac now. However I disagree with comparing the speed to Virtual PC, it is not that slow... http://blogs.zdnet.com/Apple/?p=150 On Mar 7, 2006, at 1:28 PM, Tony Johansen wrote: > On 8/3/2006 2:47 AM, "Anne Keller-Smith" <earthpigz at earthlink.net> > wrote: > >> Hi, Tony - >> >> My plan is when this machine malfunctions, I'll send it off for >> repair >> or junk it, >> then buy the next Mac with whatever OS is on it. >> >> Only question: will my programs work on the new OS with Intel?
