BACKGROUND: I came to the X2 from an htc Incredible, which I had from launch day just about a year ago. It was my first foray into Android, as well as touchscreen phones, as I had a Blackberry and Sidekick before that. Once I got used to the differences from Blackberry - the OS and touchscreen - I really loved Android and the Incredible. But after a year with the Incredible, I wanted a bigger screen and was also hoping to get better call quality/reception if possible...not to mention the gadget whore in me was getting restless
I decided against the Thunderbolt because of reports of the battery life being so bad (something I'd experienced a bit of with the Incredible) and wanting a different manufacturer for the reception/call quality issue, and against the Samsung Charge because I just don't like the way it looks and a lack of timely updates that I have read about with Samsung would probably tick me off down the road. I was interested in the Bionic, but since it seems to be buried right now I was too impatient to wait. While I would like 4G speeds right now, I didn't mind waiting for it until my next device...perhaps after battery life issues get under control.
So all that led me to the X2. I know someone with an X that I've handled briefly before an my impression of it was that it was sort of slow in transitions between screens and the UI was not nearly as fluid and elegant as Sense. But I decided to take the plunge anyway since the X2 has an upgraded processor and Blur is supposedly toned down now...plus I figured I could replicate things I liked about Sense with downloads from the market.
IMPRESSIONS: After a week of use, my two main goals - bigger screen and better calls - have been met! The jump from a 3.7 inch screen to 4.3 is great. I am happy with the resolution of the screen and think it is better than the X, but I find that in motion the screen shows artifacts and ghosting. It is definitely better than the Incredible outdoors, even when wearing polarized sunglasses.
Call quality has been excellent...a definite step up from my last phone. Callers sound loud and clear and are easy to hear even when outdoors/in a noisy environment, which was a periodic problem for me with the htc device. It also seems that I get a stronger signal at work, where I am not directly next to a window. Overall all I am pleased with the X2 as a phone.
The main thing I'm not sure I like are the hard keys for menu, home, back and search. They require definite effort to press and make noise when pressed. The chances of me accidentally hitting the back button or the home button when doing something like surfing or gaming are certainly decreased, which is a positive. But if I had a choice, I would still probably choose virtual buttons.
One thing that makes me crazy about the X2 is the inability to organize my bookmarks in the browser alphabetically. I've tried to figure it out and can't. Even made a post about it and got no answers. I can't believe this option wasn't included. That seems like OS 101 to me. Weird.
Battery life has been a mixed bag so far. One day i got 18 hours of use before the phone was at 20%, the next it was at 20% after 8 hours. Overall, I would say it is better than the Incredible and I am less nervous than before about charging. However, I still keep a charger at work and in the car.
There are a few other little things here and there where maybe the htc phone is a little more intuitive, but nothing that really stands out at the moment.
EDIT: One thing I discovered after this post was that you can't search Calendar on the device. This is probably a bigger faux pas than not being able to organize bookmarks. Luckily, like most things, there is a fix in the Market - Power Search, which is free.
