My sis' birthday is coming up next month and my parents and I are going to get her an MP3. It came down to an iPod vs Sony HDD MP3 (30GB iPod and 20GB Sony). We've ended up going for the Sony as it's cheep, she won't fill 30GB and wonldn't use it for video (she'd not have a clue how to do so anyways). Also the killer battery life from Sony is making me want one. Anyhow I'm now also looking at getting one to replace my iPod when it dies in a year or so. But I'm wondering if they work with Macs at all? I couldn't see it anywhere in tech specs on the stors I was looking at. I'm not fussed about the software, as I'll probley end up using something else (I'd love it if iTunes could work with it...). But could I just drop and play MP3 onto it? I've never used on other that borrowing my mates from school to mess about with.
