I have a Droid X and I LOVE it. Idk, I guess I'm not too concerned about the technical aspects of it, I just want it to run and run what I want it to.
It's got great specs on paper, but it's hacking community is nearly nonexistent due to its locked status. Motoblur is the devil's spawn, and it is only recently that CyanogenMod 7 was released. Put that on and the phone is great, but honestly, anything else is terrible.
for now i'd recommend Samsung Galaxy S II. gorgeous phone with tons of Droid Apps till i wait for a Nokia Win7 release.
When the (codenamed) Nexus Prime releases, that will be the phone to get. The Nexus S (4G or not) is still a fantastic phone, and will run smoother than a majority of the dual-core phones on the market today.
