A few questions: 1) How much life do you typically get out of your iPhone when using it strictly as an MP3 player (assume not a lot of song switching or playlist manipulating, just letting it play most times) 2) Same question, video? 3) Does your laptop charge the iPhone when the laptop is not plugged into the wall? (mine will not charge my iPod unless it's hooked into AC for some reason) 4) Can I have it docked (?) or charging in my laptop while at work and still use it as a phone and as an MP3 player? Obviously if it rings i'd take it off the charger, but i'm just saying, is it capable of being functional or when it's plugged in, is it rendered useless because it's hooked to a data source? I'm curious as to how functional it'll be if I can sit at my desk and use it to listen to MP3s, keep it charged, and be able to answer it if it rings. I'd like to replace my iPod with the iPhone basically since my 60 gb video is bulky and an extra device to carry. Battery life shouldn't be too big of a problem for me I suppose since i'm always seemingly near a laptop or desktop. I'd ideally be using it probably 2 hours a day where it isn't plugged in somewhere in the commute time. Thanks.
