Hey. I have a G4 iBook which is long past being my 'main' computer, an intel mini I use for server purposes (has dodgy sound, non-working superdrive) and a G5 iMac which I use for just about everything and love besides: inevitable phasing out of PPC, how loud it is, and how anything graphically intensive makes it choke. So, I'm looking to get an MBP, but can't really justify having an uh.. "collection" of macs . How viable is it to get rid of PPC stuff these days? They're great, working computers, but is anyone buying them considering PPC support's days are numbered?
