I've always thought about something like these. What's the battery life like on this model?

Something like 3-4 hours. Not great, but not bad either, given my usage profile (I charge it every couple of days).

I feel like I'd end up using it on the tram to/from work or at lunch, so that might work for me. I've fought the urge to get one for a while, because I can't accurately assess whether I would genuinely use it, or if my brain just wants the cool nerdy thing :)
