No, they aren't obsolete, Verizon (and sprint as well) just ignores Windows Phone 7 lame reasons.  Yes DROID works fine for what you want but it is certainly not the best and most elegant solution.

If you want a newer windows phone now (something besides the trophy) I'd recommend moving to t-mobile or at&t they currently have much better options here in the USA.  Either that or wait for the Windows Phone 8 devices to ship out later this year.
