Well I got to play around with my buddies Iphone 4 side by side with my Droid 2.
Almost completely different animals.
Iphone Pros:
Easier to navigate (maybe to me cause I have an Ipad)
More apps (that I find interesting anyway)
Less likely to have issues (from reviews)
Itunes
Battery Life
Iphone Cons:
Verizon can't do a damn thing with the phone, if something does happen, you gotta send it to apple.
If you don't have the apple car insurance, they charge you just to talk to you on the phone. (had this happen with my Ipod)
Not near as many Free apps as Droid
Droid Pros:
Tons of free apps
the FREE navigation is hands down better than the iphone's paid or even my TomTom
I was able to import my Itunes Library to my phone
Droid Cons:
Battery Life
My Droid 2 had keyboard issues (just once in a while)
SO, they each have their place. My goal was to get rid of my Ipod and TomTom and get down to one device in my car except for XM radio.
It was time to upgrade phones yesterday and after much deliberation I went with another Droid. The HTC Thunderbolt. It has 40 gigs of storage, I was able to put my Itunes library on it. I hope I don't regret it.
They really are both great platforms and I like both, but only need one.
For me the Navigation on the Droid was what did it for me. The HTC also has a LOT better camera and records video in 720P (the Iphone may as well I don't know)
Thanks for all the info and opinions everyone.
