Getting soon, some questions...

it is big there is no way we can say otherwise even the box it comes in says the dimensions are big by big lol.
but i think it feels good in the hand when doing portrait typing, find it hard to do landscape because i use swype (instead of normal typing). I don't think it is that big because I am used to it, others that see it are most likely thing "omg it's going to eat me!!" or something like that.

there are loads of apps, I've heard 30k+ but they are hard to find, the marketplace is pretty empty and over priced but there are many websites that provide free apps, also the XDA forum but it is a hard to find something in that forum.

I get some lag sometimes but only because I mess up my phone and don't hard reset it or fix it. When I've not broken it, it works fine and is super fast.

Battery, you'll get a varied response. Yesterday I finished my third day and put it on charge at 9% before i slept (would have lasted the night. Usually I get 2 days which includes watching an hour+ of tv and regular phone use.. and playing use.
Today I've used 11% and used it for a few calls. My battery has gotten better over the 2 months.

Camera flash is bright, if you aren't careful planes will think you are signalling them to land.
(too bright for up-close shots)

There are a few US users here so you should have an answer on EDGE use soon.

It is probably the heaviest phone around, but the weight is very well distributed and feels good and solid. The iphone feels so light after using this, and it feels cheap :S. When the phone is in hand I can't feel the weight, but when it is in the pocket it may cause the jeans to fall.

hope this helps also check out the reviews section alot of our members have posted detailed thoughts that you will find useful.

Thanks a lot for the responses guys! Im not sure which phone to get, The only thing im worried about is the size, Im worried that it might be too big for me, it it was a bit smaller I'd buy in a second, I wish I could see it in person. Again thanks!

It's very slightly thinner than the original iPhone.
It's Wide by Wide, but thinner than most smartphones out there.
As long as you don't wear really tight pants, you'll be ok.

Big screen = GREAT.
Big screen AND thin? = Hell yes!

Sounds like you got your questions answered. I use hd2 on edge in Idaho, It's ok for what i do,weather apps, gps,all great. youtube on skyfire is ok, sometimes little slow loading. But most places i get wi-fi. i used htc hd before, it was really nice, but this hd2 is "WOW!!  size I think is fine, not been a prob, best phone I've ever had,,Quig   

This will be my next phone as well.
As SOON as T-mobile announces it, I'm there with my wallet open.

Im currently on a Family plan on ATT, I can get out of ATT if I wanted but Im not sure what to do.

Same bad coverage here with Tmobile.
