It looks to be about the same as my Pre- where I live, just outside of Houston.
Wifi is also fine so far, a little less than what I get on my laptop, but not a problem.
Aww. Sad moment. I've been charging my ET with my Pre USB cord, and my Pre just bonged to let me know it needed some juice too. Poor little Pre.
So far, versus Pre, I love how fast web pages load (even over Wifi Pre is slow to render). The touchscreen works far better than the Pre's -- no lag when scrolling, or need to press buttons twice to make sure they're working. I love having Skype and Netflix available. And I love the look of the screen -- just gorgeous.
On the negative side, I hate how long this thing is taking to charge, though the battery life is far better than the Pre once it is charged. That's a tradeoff I can live with. What I REALLY hate is the onscreen keyboard. I was trying to fill in a text field that was at the bottom of a web page, and the onscreen keyboard sat itself on top so there was no way to see what I was typing. And it keeps trying to change things like usernames into words. Grrr! Hopefully some of that is a "user education" issue. I am used to typing one-handed on the Pre. I'll have to see if I can still do that with the ET. The level of accuracy required for an on-screen keyboard is much higher because you can't feel your way along to the right key.
I've said more on the negative side here, because it is specific to the transition from the Pre, which you asked about, and also because there's already excellent coverage of the positives of this phone. Don't get me wrong though -- I love the ET, and there's not a question in my mind of taking it back.
If you have more questions from a Pre perspective, just ask.
