I've used Macs since the 80s, and, to be hoinest, until OSX 10.2 came out, it would have been a hard sell to get people away from Windows. OS9 was way behind what it should have been and 10.0-10.1 couldn't even play DVDs. I bought a G4 Tower (G4-400/AGP with OS8) the month they came out and loved it, but I secretly knew we Mac users were losing the race. I got OSX Public Beta and knew it was the future, but it took a few releases before we could truly lord it over the XP-heads.
I'm typing this on my dual 2GHz G5 (bought shortly after they came out ... I seem to be into these towers at release date - roll on the Intel PowerMac!) and love doing all my photo stuff one minute and boom, getting down and dirty with sed/awk/grep or a perlscript on the UNIX command line. It's the machine for the creative in me that loves to play and the geek in me that pays the rent.
Welcome, Slay. You're in for a fun ride.
Spot the Mac G5 on the left plugged into my 24" widescreen LCD. The PC on the right hasn't been started since ... ooh, last time I needed to play R-Factor.
