To make a long story short, I don't have a data plan for my phone which is why I use TomTom for GPS (maps stored locally). In theory that should continue to work even when the phone itself is deactivated.
I've been waiting for a good QWERTY android phone. The Xperia II, if it's actually an android phone (and not WinMo as I'd heard) would do nicely. I do a lot of work "in the field" and being able to type up quick emails and documents would be nice. Too bad the Lancaster isn't spec'd as well as the Hero, or I'd consider that too. If the rumors of Sprint getting the Hero are true, there's a small chance they'll get a QWERTY version eventually, or something similar. The Touch Pro2 would be an option if it were fully functional under 'droid as well.
