I just got mine yesterday, so it's been a short week for me. So far the learning curve is really short, much shorter than it was for me with my Q. This thing is very well thought out with regards to the user interface.
I was just thinking that today. I've owned lots of smartphones and I have to say that this is first one that a week later I'm even happier with then when I bought it.
Today I had my first real world "calamari ad" usage. I needed some cards, looked up a place near work with google maps, called them to make sure which side of the road they were on, went there, starting to look a sandwich place for lunch, answered a call, finished the search and got lunch.
While this would be technically possible with other devices I've had, they are so clunky to do this I would never have bothered.
Not bad, considering I still can't get the phone to appear in itunes, and I have to use 2 other computers to do my syncing. Other than that I like the phone and haven't really experienced some of the problems that I read about on here.
I got mine earlier this morning and I already love this thing. Personally I don't see why people are having a hard time typing I can already type with two thumbs fairly easy. But I think the whole interface is amazing I wouldn't trade it for anything.
I got mine on iday also. I think it is definitely one of the best cell phones ever made. Also, this thing will be amazing when the updates come. Which will hopefully be pretty soon.
