I'm currently on a Blackberry 8700 that my company pays for. After picking up a Droid Eris for my wife I became extremely jealous as I realized my Blackberry is crap. I'd have to start paying for my own phone if I went with the Droid so it'd really have to be worth it. When rifling through Verizon's site to add this phone and additional line I noticed there are 2 options for Web. The expensive one mentions "Corporate E-mail". Would I need this option to talk to my company's Exchange Server? (Yes, I checked with my company and they have the appropriate Exchange connector). How well does this device work as a mass storage MP3 player? I know battery life is a concern with this phone but would it be usable for the commute back and forth to work? I'd be getting the 32G SD card for storage. How good is the GPS? Could I use it for tracking and mapping my mountain bike trips? I don't care if it's super accurate but it would have to be usable? Are there are any VPN apps? I know the Iphone has a Cisco VPN client. I wouldn't mind being able to hook into work.
