Ok, I gave up and installed Jaguar in my dual 500. I place the OS in one of the partitions. Now, there are lots of good things, nothing that I was looking for really. The real impruvment is the multitasking function and things run smoothly and it is more stable but... I have 3 computers, the dual G4 500 with 320 of ram and the 2 Poerbooks G3 500 with 250MB of ram each. I'm runing a software calle Artmatic Pro 3 for OSX in the dual and the 2.5 for clasic on the Pismos. Now, the dual is 1/3 slower than the Pismos. I mean 2 G4 500, more ram, OSX and it is slower? besides that I do not see any plication runing faster under OSX, Quicktime movies freezes between frames as it does in Clasic and I can tell there are a few good things but Clasic still a much reliable system. I still not able to use my epson printer under OSX, neither the Agfa scanner, forget about the Aurora video capture card. It is a mistake to jump a 100% in to OSX yet, personally I do not recomend it. Now, by the end of the year I may see something that would be a good investment, but for now if you make me choose between the latest Mac and the lates PC I will take the PC, I can do more with it than with the Mac. Now, I'm a powerbook person, no laptop is gonna make me doub about powerbooks. I think the 12" fully loaded is a hit.
