iMac Classic G3's becoming unuseable by todays software
The old G3's are dying very fast. I have a old iMac G3 classic, and I can't run Final Cut Express, Final Cut pro, or GarageBand (I could, but w/o live feedback). There's a bunch of others out there too, like Maya (to expensive for my pocket) and a ton of other software titles that require a G4. All this new software and probably Mac OS X will all require G4's, and all the G3 users will be in the same postion Mac OS 9 users are.
