I wish just once I could see the magic G4 500's that run "You Tube" just fine. I have G4's from G4 500, 867, 800, 1.0, 1.2, and 1.25GHz not one of them will play a smooth You Tube flick.
I agree, but it may not be the CPU that's the bottleneck, it might be the GPU (video card). I've got an overclocked 1.58 GHz Mini that's constricted with the built-in 32MB Radeon 9200 video card. When the Mini is attached to an HDTV @ 1920x1080 it stutters and chokes like crazy on almost any higher resolution video (actually almost all video). If I run at a lower resolution (say 800x600 stretched) it plays much more smoothly with the same resolution videos, BUT, the ONLY native resolution that's not "stretched" is 1920x1080. I interpret this as 1920x1080 being roughly 2MB per frame, so the 32MB video card has room for about 16 frames, or 1/2 second HD video, so no wonder it chokes and stutters. I believe if this Mini had a large 128MB or 256MB video card the playback of video (including YouTube streams) would be significantly better, perhaps even dead smooth? I believe a slower G4 with a sufficiently large and fast video card might possibly be a "magic G4", but 500MHz is a little too slow. A 1.25GHz with a fast & large card might be the "magic G4", but the need for Leopard will slow that now, so it appears the days of the "magic G4" are indeed numbered, and soon extinct.
