I had tried my friends' and co-workers' Windows Mobile phones and really disliked them, I stayed on dumb phones for years, I wasn't big on texting and didn't want to move to AT&T so I wasn't going to go to a Smart Phone as iPhone was the only option back then. But then in 20(09?) I tried the HTC Droid Incredible and fell in love with that phone. Picked it up shortly after it was released which was more difficult than I would have thought because they were selling so fast.
Something about that phone that spoiled me was that the release models had an AMOLED screen. The screen was a Samsung and was the best screen on a smart phone at the time. Shortly after the release Samsung brought out it's new phones and stopped selling the screens to HTC (or some disagreement). The LCD replacement was terrible, and I saw this trend in other Android phones.
My love for the Incredible started to die after waiting forever for updates, in fact it was a full year after the 2.3 release that it came to my phone, which was the same week that I ordered an off-contract HTC Trophy from Ebay. I really didn't want to give up my AMOLED screen but really wanted to try WP7 because my co-workers were all using it (we're Microsoft developers). The Incredible also had issues after it's Froyo update that my texts would sometimes go to the wrong person. (When I pressed send I could actually see the contact in the contacts list CHANGE). Also constant crashes and restarts and hacks to try to make the phone work correctly...
I love WP7, unfortunately the Trophy is not my favorite phone, it is the same hardware as the outdated HTC Incredible but had a lower end screen and camera. The HTC Incredible had the BEST camera on a US Android Handset for its time, and I'm sure was better than any other US Carrier smart phone including the iPhone. I don't get how this didn't have more publicity but whatever, it is long past now. And seeing how it is long past I'm disappointed with cameras on phones yet today.
I have my Lumia 900 on pre-order, I am switching to AT&T and had the handset ordered at a price of $0. I really really can't wait. I do wish the resolution of the screen was higher (since I'm going to a bigger screen but same resolution) but atleast it is better screen techonology so I really can't wait to play with it and as long as you don't hold it right up to your face I'm sure that the screen will look beautiful. The other disappointment is the camera, it looks excellent in well lit situations but it's low-light is worse than expected. We will see how it fairs but it is looking worse in low light than my Incredible was. I guess there is nothing to do there as there isn't much competition.
I also have a feeling with WP7 that there is an issue with the camera software itself. It seems like none of the phones take very good pictures and I'd really expect the Focus S to be better than it is. The Focus S is an excellent phone, and if the Lumia hadn't been coming I would have probably switched to that in June when my Verizon contract is up. That being said, I'll be paying an early termination fee to switch to AT&T which I'm sure is their intent with the $100 off for new subscribers deal.
One last gripe which I have meantioned previously is the location of the charge and headphone port. I really do wish the charge port was on the bottom of the phone. It seems like with the speaker placement it should be on the top, but I fully understand why it is on the bottom, because most commonly people will put the phone down in front or to the side of them when using speaker phone. Again with the charge port on top, this phone is not dockable without some creativity or if the OS can rotate upside down in portrait, which would be acceptable. And I really think the Zune HD nailed having the headphone port on the bottom, it made the headphones wires less of a mess.
