I have only ever owned an iPod Nano and I have taken it for granted that in order to switch it on you press play and the screen comes on instantly. The other day however my father showed me his Samsung MP3 player, flash-based, and it had to boot-up like a computer. I was gob-smacked that one of the kings of flash-memory couldn't utilize it in the same way Apple does. It made me try and remember how long a full-size iPod takes, but I'd always thought that was instant as well (am I wrong?). What about Zune? How long does that take to start from sleeping?
