I'm curious: how well do some of the later G4 and G5's perform these days, especially for flash-based (or even HTML5) things like watching YouTube videos & Netflix? A few months ago, I was trying to update a G3 iMac, but I couldn't get it to play Youtube videos. How true is this of later Power PCs? I ask because I'm (still) looking for a suitable computer for my kids. Power PCs can be bought at quite a decent price (there's a G5 1.8 going for $50 on my local Craigslist!) and were great machines back in the day, but if Flash is an issue, I may look for Intel computers only.
