You still haven't clarified what exactly you want to do with your 64-bit system, besides win dicksize wars. Reasons for using a 64-bit system include, for example, *needing* more than 4 GB of RAM. If you want to do stuff like Ron and Nemo have done, where you stick your entire filesystem in 64 GB of memory or so, then yeah it's important. On the other hand, I've never had a Plan 9 system with more than 4 GB of RAM, excepting our NIX test box, and everything has been fine--you don't need a lot for this OS! >> I don't even know what you're attempting to imply with that >> calculation at the end, though.

Software graphics are slow. > I'm not that familiar with how the Plan 9 graphics system works, but we're not talking about hardware vs software OpenGL. There is no OpenGL to be had here. This is writing bits into a framebuffer and having them appear on the screen. It's pretty damn fast to write things to main memory. john
