I'm not totally anti apple or anything, I just don't feel a need to pay an apple tax For me, desktop Linux is more than good enough. I installed linux (FC3 to be exact) on my IBM T42, and other than a mild bit of hoop jumping for the wireless networking, requiring me to download a set of files and toss them into my kernel modules directory, everthing was auto configured, and just worked.
I own an iPod shuffle that my company gave to everyone, and it's a pretty decent little player, but I've never used iTunes, as they don't, as far as I know, support Linux. Plus I'm not paying someone else to encode mp3s for me, when I can pay less to buy the CD and burn it myself, and have it in both CD and mp3 format. Have you ever used Grip? it's very nice. Put in a CD, tell it to rip and encode, and 5 or 10 minutes later you've got mp3s ready to install on your mp3 player.
I guess if I was a graphic artist, I'd likely have a Mac, but I'm not, so the Gimp is good enough for me, I guess.
