An impression from someone who doesn't have internet access at all yet:

Maps is terrible. It obviously has addresses in its database but you go to search for an address with the internet connection off and you type only 1 character and it says it can't find anything. I can't figure out what the little building icon is for. And the application eventually locks up and while the app can be killed it won't work again until the phone is restarted.

I like the GUI a lot so far. It is very slick. A little unhappy the full screen button is no longer there but I'll probably get used to it.

I like that there's now a task list and better calendar included; however the task list does not displace gpe for me because there are no categories and no method to assign a task independent of a date.

Taking the back off of the phone was scary the first time because it seemed like it was going to break.

I can't figure out if tmobile is working or not and I don't have wireless access right now either.
