I'm a new user of a pre-owned HP 2490, and Battery life is Excellent. I love email, and have the WiFi on only with Send/Receive. As yet, I don't have any 3rd party Apps, and I intend to keep these to a minimum. Here's a Preference: I'm not a fan of surfing the Net with devices having 3.5 inch screens.

I still have the Palm T3, a good PDA, but battery life was poor from the getgo.
