I've had the Window's Mobile VX6800 for years, but this Android operating system and the Droid 2 is all NEW to me. Lots to learn. At this time, I don't think I'm going to use a lot of bandwidth so I only signed up for the 150 megs of data. I'll see how that goes. I'm not into (yet?) video or music on the Droid 2 and don't do much texting yet. So, I think I'll be OK with the 150 MB.
