It goes without saying that I’m happy with my new workstation. I went from a 450MHz PPC750 (G3) to a dual 1.8GHz PPC970 (G5) with Quartz hardware-acceleration. I really haven’t done anything particularly compute intensive, but the difference in my ordinary, day to day tasks is just striking. Things I would actively avoid doing (using my ISPs Flash-encrusted homepage, for example) on the G3 happen instantaneously. Apple Mail is fast enough for me to use without reservation, reindexing of large folders is instantaneous, etc.
I’m still trying to build my working environment up, of course. I have to bring sure all my tools and scripts and everything else over, and I’ve got to figure out how to sync my Tungsten, etc., but it’s a joy when I don’t have to wait. At all.
You can’t get there from here.
