I played around with my friends new droid X that he waited in line for lol. He said there were only three other people when it opened.
It seems like a good phone but it keeps slipping out of my hand I just know I'm going to drop it.
The os itself seems unorganized, I have swipe through a bunch of screens to get to where I want. The apps aren't refined.
I actually did a battle with barcode reader apps of all things, mine read everything, his maybe got half correct. I tested the camera side by side in still and video and the iPhone won both times, it has much better color. I do like the button for the camera on the droid though, makes holding it still a lot easier.
Couldn't really compare battery life but before my last charge I had 7:15 of usage and 2:12:00 of standby.
I was envious of the notification bar though.
The screens look about the same until you look at small text on webpages and thats where the iPhone really kicks ass.
The OS seems jittery when swiping through home screens and abrupt when scrolling and zooming.
I like swype on the droid but typing on the iPhone still seems faster but that may be because I'm used to the iPhone.
He also had a free tethering app that probably would be rejected if verizon found out about it.
And lastly you can host conference calls on skype, something you can't do on the iPhone

.
In general, the droid X excels in some areas but you're not going to find anything more refined and user friendly than an iPhone.
