I have 2. The LG Dare is my daily phone and I also have an XV6800 for internet and email push. I also use a Garmin Mobile XT 20 card in it and cracked the GPS radio so it would work without a bluetooth receiver.
Actually had good luck with it, so I am going to give my new Droid a try. I am waiting for it to arrive. I am torn between it and the Imagio. Mainly for the Mobile TV, but seems like the appstore will be a big change from having to pay for everything on a Pocket PC.
