yes, I echo Frisco's last words there. For me I came from a Windows Mobile 6.5 phone which the OS sucked really badly. You HAD to customize it and add a different ROM for it to work halfway decent. It was very frustrating. I have also been with Verizon for awhile now so I'm grandfathered into the unlimited data plan and probably plan to stick with them for awhile. Knowing that I am comfortable tinkering with phones and my technical level of expertise I chose Android over the iphone. I almost bought the Thunderbolt but I started to see how much battery life they were having and I thought that I wouldn't want to go back into a situation where I would have to tinker with it just for it to work decent.
Research is best. If you are buying on contract consider that you may have to stick with the phone for 2 years, or pay more for a new phone sooner than later, so to me it's at least a 2-year investment. Originally I wanted to wait for the Bionic but I ran out of patience thinking that they would not have fixed the battery issues. Now it's Verizon's best 4G phone at the moment. The longer you wait the better models come out that you can compare with what you would also consider, and those other phones may become cheaper in lieu of newer phones coming out.
Also consider that low-end cheaper phones tend not to keep a support track in terms of the carrier offering updates. I have been hearing whispers that some Gingerbread phones will get an Ice Cream Sandwich (Android 4.0) update. It's still too early to speculate on the droid x2 though.
Also, check out the
XDA-Developers forums thread. It is a great place to gage the community developers forum and what phones continue to get ROM updates and which ones don't. I learned the hard way that with the Windows Mobile 6.5 devices the HTC Touch Pro 2 had a whole heap of support as compared to the HTC Imagio, which were virtually the same device except for the keyboard. Had I chosen the Touch Pro 2 I would have enjoyed the benefits of tons and tons of great ROMs.. and Android ROMs but again, I digress. See which phones get the most attention and which ones don't and which ones people have a lot of problems with.
