I just became eligible for an upgrade with Verizon, and I'm considering getting a Droid X after it comes out.
It will be a HUGE change for me, as I only use my current phone for talking and occasionally checking email. Lately, I've been frustrated with my netbook. It's extremely slow, even when there's a good wifi signal. I'm thinking, "Why not ditch the netbook for a smartphone? Then I won't be at the mercy of sketchy wifi when I'm traveling."
Online chatter says the Droid X will probably replace the HTC Droid Incredible, which has supply problems and is out of stock until later in July.
