i have the droidx and love it, the droid also has flash player dowloadable off the app market, which really opens up the stuff you can do on the net, iphone does not, since it is a windows program, i have a 8 megapixel camera, iphone is a 5, the google os has a lot more apps, i have a program on my phone called lookout, which is a free app, and scans each app you download before you its installed letting you know if it is safe or not.
i ported all my songs from itunes to my droidx, so it uses itunes just the same as the iphone, the iphone is limited to the memory it comes with, the droid come with about 22 gigs, but you can take out the SD card and put a 64 gig and have 70gigs of memory which is more than you could ever use.
But, im prolly going to get the iphone just to try it out, i work construction and the droid is a bigger phone, and im afraid to break it crawling around on iron beams, thats the only con i can think of, i love the droidx, it does more than ill ever need. Also the navigtion system is better than the iphone, me and my buddy on the way to NC had both our nav systems running on our phones, my phone said one way, his said another, him thinking the iphone is law, he took the way his phone said, i zoomed out on the map and showed him the way his phone was taking, and it took us out of the way 6 miles, just to connect back to the road were already on
Having google maps is nice lol,
But it falls down to your choice, the touch screen on the iphone may be a little better, but not so much that you would notice a big difference, the touch screen on my phone never gives me any problems, so im happy
