About 'switching' (very popular term, used a lot by Apple):
I recently 'switched' on work, from Mac OS 9 to Mac OSX. The results are good, now i can do more tasks simultaneously, such printing long sizer postcript files and convert to CMYK on Photoshop; the print jobs now are much faster. I also use a good enhanced desktop

(not intuitive as OS9, but have a lot of improvements).
I'm trying to 'switch' on my home. On my Intel computer, i installed recently a Linux distro, and i'm very impressed: good desktop, i can run Some Windows apps, faster performance (and i have not well installed the driver-monitor modules!). Not all are happy on WIndows, sometimes i need to use the Terminal, but there's no problem to do all tasks, includig designing and painting.
I also checked my Mac computer, crashed recently, and my problem are the CD drive. For low cost, i can run again my Mac at home. Don't surprise if i don't upload some skins/icons here on the next months.
