Since I started with macs at around OS X (ver 10.3), I've found that I can't use another OS for a desktop. At work, I've tried running Fedora Core 4 and Windows XP -- but it really didn't feel good. Now I bring in my own personal Powerbook with Tiger to work every day. To save me from having to bring my 'book to work every day, I tried to install Mac OS 10.2.8 on a G4 tower. 733mhz, 640 megs ram, and ran somewhat slow. Was Panther just more optomized and smoother than Jaguar, or is this a hardware thing? I recall a coworker with a slower G3 based iBook (the new white case style, though) and it ran 10.3 pretty lively. In any event, I'm still taking the laptop to work. Anyone else notice they are now "stuck" with Mac OS?
