Most people thinking about buying PowerPC Macs know that they are not going to be perfect at everything. But they usually don't know exactly what there not great at. SO having used a PPC Mac for a while now heres some things that they suck at, that if you need in a computer I would reccommend trying to find another option.
Flash
There are work arounds somethings like Youtube, but for the most part PowerPC Sucks at doing anything related to Flash, unless your on a Quad G5 your gonna have a bad time.
Java
The little java things it does fine, but for something big, like say runescape or minecraft , your gonna have a bad time.
Games
By this I mean availablity and varity of games. Most Macs play the games that work on them Amazingly. Its just that your not going to find many for them.
New Applications
Newer Apps probably won't work. That thing that your really need? Doubt it. BUT there are useually older versions of the app you need that do work with PPC though you might lose some features. If you really really REALLY need "Insert App Name Here" Make sure it is compatiable with PowerPC
