Yup... G3 just doesn't cut it for browsing modern sites anymore.
Even my PowerMac G4 DP 867Mhz has issues with YouTube at times, and to watch videos with a decent framerate on Hulu or certain other sites, I've got to set the Flash video quality to "Low".
New (or rather, refurb) iMac on the way, though 🙂
All my family's old G3s are kicking around doing DVD playback & kids games and such now. Except my poor old PowerMac G3 266Mhz with a *gasp* Voodoo3... it's just sitting in a corner, sadly reminiscing over the days when it used to serve up serious fragging in Unreal Tournament and Quake 3 Team Fortress 😛
Oy, I've digressed!
