Now that it's live, I was able to handle an EVO in the store today. I quite liked it. I haven't committed for sure, as I still have 2 months on AT&T with my iPhone 3G.

Size
The EVO felt in my hand to be about the same size as my iPhone - which is interesting because so many reviewers made a huge deal about it's size being too big. Seriously, this is a non-issue. The size is the same as an iPhone in a slim silicone protective case, actually a little smaller. I'm sure it'll bulk up if you put a case on the EVO, so OK, if that's a big deal, don't put a case on it.

Screen
The huge screen was nice - real nice. It wasn't the ray of light from heaven that so many reviews made it out to be. But it does make my iPhone screen look tiny and humble. I bet once you go with something like this, it'll be tough to step back down to a smaller standard size screen.

Interface
Some of the interfacing is going to take time to adjust. I was typing some text, and missed a space. So I touched the text area expecting a bubble to pop up, a la iPhone, and roll around to find the spot, and insert the space. Instead I got a pop-up menu and ended up cutting most of my text . I think you're supposed to use the arrow keys on the keyboard to move around. Which seems silly - it's a touch screen, why use arrows?

Street Nav
The built in turn-by-turn navigation looks really cool - with voice guidance to boot. With a screen bigger than some TomTom's. iPhone doesn't come with this built in! But I have to say, I like the way the iPhone has integrated maps, directions, and searching all into the one program. On the Android, you have to use one app to look up say Angelo's Pizza, which will then give you directions to it. But if you want to see landmarks along the way, via satellite images, then you had to go to another map app. Which doesn't have the built in ability to just type in a business name and look it up. A lack of polish in interface, where Apple shines.

General GPS use
But I like having multiple pins show up on my map. For example, if I'm hunting, and there are multiple blinds in my area. I'd like to have the ability to see position on the satellite map via GPS (street maps are useless in the woods). And I want to see where all the blinds are via tacks at the same time. On the iPhone, you can only see one tack at a time. I'm hoping with Android you can see multiple.

Phone
Phone quality seemed fine. I called Deanna's phone and it worked. Which amazed me, because she's on AT&T - and so normally in paperweight mode.

Camera
The camera was good - very serviceable and a big improvement over my 2MP iPhone camera. But for an 8 MP camera, I wasn't very impressed. Unlikely that it will be taking many wallpaper photos.

Speed
At last, 3G speed - ironically in a 4G phone. In central WI, I'm doomed to forever be one step slower than what's out there. Processor speed was great, making it pleasant to use.

Cost
The phone cost is quite reasonable (~$300 minus $100 after a silly rebate game) - about the same as most other high-end cell phones, and cheaper than a few. But the extra $10/month 4G charge (in a zone that will not be getting 4G) is irksome. Basically, the phone costs an extra $240 because of this. Annoying. But in totality, 2 year cost of ownership still sounds like it's going to be competitive, and probably cheaper than a comparable iPhone or Verizon plans. Plus 8 GB or RAM is lame - so figure another $75 for a 32 MB MicroSD card. I figure 2 year cost of ownership is somewhere around $2200. (How much are you paying now for 2 yrs of ownership?)

$30/month to make it a mobile hot-spot isn't going to happen (=$600 adder to 2 yr cost of ownership bottom line). But you can opt in/out at will - so who knows, if I'm on a trip somewhere with others. I can see me turning it on for that month if I can VPN my work PC through it - hotel internet access can be as much as $20/DAY.

Battery life
No idea, it was plugged in the whole time. It's a smart phone, only a fool expects a smartphone to last very long in use without being near a charger or spare battery. I'm figuring maybe 2 hours of GPS usage, so when I'm out in the field, I'll be bringing a charger pack. When only used as an idle phone, I expect it to last at least 2 days between charges - but based on some reviews, I may get much less. Concerning, but manageable.

Compatability
One thing - all my iPhone/iPod docking stations and integrated devices will become expensive night lights. I wonder, do they make adapters that slip into and connect to the iPod sized docking stations, that you can then slip an EVO into?

Will I buy one?
Probably. This makes my iPhone 3G seem pretty dopey. Even the iPhone 4 shown on Gizmodo looks to be a step below this unit.
-AT&T is a poor service provider in my region, and offer no coverage for Deanna's drive or city of employment. So they, and the iPhone with it, are out. That, and I just don't see what the iPhone is going to have that this wont.
-Verizon won't even sell me a phone in my Zip code (and they're reportedly expensive for a good smartphone plan) - so they're out.
-Which leaves Sprint. I don't see Sprint coming out with an even better phone than this in the next 2 months. That, and this is a really sweet phone.
