If you could only have one feature (i know this would never happen and you probably would never buy it for one good feature but just bare with me) what could you not live without on your iPhone and y? i wish i had an iPhone.....
I love the touch screen! In fact I logged into iTunes on my MacBook Pro last night and actually touched the screen. Nothing happened. I'm really starting to get used to the screen. It's amazing how fast you can assimilate.
Google maps have saved my butt twice already! I think thats the next best thing to GPS, and in conjunction with it, unstoppable. Yes, the UI is great too! Im surprised how responsive it is, its almost exactly as was displayed at the keynote...no hype left unanswered!
I really love the Google Maps widget! It keeps my wife in check when she's driving around town hunting for places to go.
However, when I was getting ready to get the iPhone and reading up on it, one of the features I thought to be least useful was the YouTube widget. I've always gotten on YouTube occasionally when someone would share a video with me, and I think it's a great site. But I never found myself using it too often. When I got my iPhone, I let my wife go out with her friends, and I found myself sitting on the couch with a beer for over 2 hours playing with YouTube. That crap is addicting.
Now if they would get cracking on converting all the videos to iPhone style!
