Guys, I've switched to mac recently and I need a voice recorder/mp3 player. I'd be down to get an iPod, but they don't record! And who wants to lug around, and pay for, a giant extension to my ipod that already costs double what the others cost? After looking at various review sites, I'm leaning towards the sansa clip, zen stone, or zen. have any of you used these with your Macs? Have you tried out the voice recording features?
