Not to start a mac vs. pc thing here (or even mac vs. pc vs. linux god forbid) but when you use a frontend, the underlying OS is completely irrelevant. I see XP for like a second before RR loads up and my music is there. If you want to be uber cool change the boot screen to OSX boot screen and change the windows chime to OSX chime. It really doesnt matter. A frontend is
designed to cover up the OS, so why not choose the best front end regardless of OS. And I hate to break it to you, but since the mac went intel, they arent so special anymore...
If there was a really cool linux frontend, then I would switch to linux. why? because it doesnt matter what is underneath! And dont say security flaws and not-reliable. I have had a BSOD once maybe twice in a year and I am a delivery driver (6 hours a day in my car). And both times were when I was running on flaky cheapo memory to begin with. Put in better RAM, and stable as a rock.
I dont want to sound mean, or anything, but really my question is what difference does the OS make if the entire purpose of a frontend is to cover it up anyways!
Of course if you have a pre-intel mac, then I guess you are screwed...
