First impressions - Feels like a nice phone. Good build quality, feels like solid construction. Looks pretty nice too. It is thinner than I thought it would be from pictures people have posted online. Seems to be about the same size as the droid charge, but a little bit thinner. It's definitely quick. Scrolling through screens, opening
apps, etc all happen immediately with no noticeable lag.
Can't speak to battery life yet, but I have the worst experience with batteries in my office building. I have very intermittent service so my phones are constantly trying to establish a connection as the service wafts in and out. So far I've gotten an hour and a half on 20% battery life with pretty minimal use. So I would say that is actually pretty good by comparison given my circumstances. As a comparison, the droid charge which I was using previously yesterday went from fully charged at 8AM, to 8% remaining by 12PM. So only roughly 4 hours maybe 4.5 hours for a full charge, so the bionic would give me 7.5 hours at the rate it is currently going so nearly double.
The vibration seems strong. I don't think I will have any issues with feeling a notification vibrate in my pocket with this thing.
Notification light is pretty small, but I find it to be much more visible and easier to see from different angles than the notification light on the HTC Thunderbolt.
The screen - I know it's a big sticking point for many and there are many strongly opinioned people regarding pentile displays. Much to my disappointment...I do notice the pentile nature of the display and I'm not a huge fan. Everything does sort of have a pixely nature to it and like there's a very fine crosshatch mark over everything. Things that are supposed to be white are
kind of white and maybe a little grey looking. It's worse when I move the device around a bit. I find that if I look at it without moving it then some of what I'm seeing as crosshatching fades away, but as soon as I start to move it I notice it again. Things that are colored look worse - so like the phone icon is green, but to my eye it looks like green pixel alternated with a black/grey pixel repeated over and over so that I can see almost a checkerboard pattern. Yes it reads "Green" to me, but it's definitely not just flat green. I am also not an eagle-eye or anything like that, just my observation.
With all that said- It's not a killer for me. I value performance first and so far this device performs! I'm also coming from a droid charge which I think has a great screen. I definitely miss the deep, true black rendering of the charge which made it difficult for me to see where the bezel ended and the screen began.
All in all I think it is a worthwhile device with a lot of power. I'm sure as I break it in a bit it will continue to get better and I can only imagine how speedy it will be once the developer community tinkers with it some more.
