I have used an iPhone since the original came out almost five years ago. I realized that I have never spent any time on what have become the other two big operating systems (WP7 and Android) in that time. Last night I went out and purchased the new Nokia Lumia 900. I think most would call this the current WP7 flagship device. The reviews have been very solid for the device and at $450 w/o contract it is fairly cheap to boot, IMO. If there are any other Windows Phone users on this forum I would love to get some tips and tricks as I try to start navigating the device or if there are some solutions to the problems I have found with it below. Here are my initial thoughts: The phone itself is solid. It has a nice build and while it is a little larger than I would like is not as big in my pocket as I thought it would be. Not a fan of the dedicated camera button as I just don't use it very much. Of course LTE is a nice jump in speed as well. The screen is decent, though noticeably worse than the last two iPhones. This is especially true when I am trying to read text in IE or in emails. IE is just garbage compared to Mobile Safari. Text renders horribly and it seems slower as I move around pages and as they load (wifi vs wifi). Also I don't like how there is no back button. Now I know there is the hardware back button though if I leave IE and go to respond to a text. Then look something up on a map, and then go back to IE, I can't go back to the previous webpage because if I hit back it takes me back to the maps. It is also really annoying that you can't lock the screen rotation. If the screen rotates you have to hunt for the back button which is now in a new location because it affixed to the hardware. Is there any way in mail to get photos/html to automatically download? Call quality is very good I think. With that said, the system has a really stupid, what I would call a bug, where if you turn down sounds so that you don't hear the keyboard clicking or angry birds chirping, you can't hear sound in apps where you obviously need sounds. For example, I have to turn up the sound back up to hear a visual voicemail or use Skype even, (I am not using the speaker in this case even). I don't like how you can be half in an app. It creates a very bizarre and inconsistent user experience so far. To illustrate, if I search something, say "Mexican food in San Francisco", Bing will give me a list of restaurants. I can then click on one and select to see the reviews in the Yelp app. However while I am in Yelp, I am not int the full Yelp app instead just some little portion of it that will only show me Mexican food places. I can't hit something to now quickly search something new in Yelp, I have to back out and search through Bing or go and open the full Yelp app. I am not going to abandon ship just yet. I think I will give a full week with the phone to see how it works out before I make the ultimate decision of holding on to it or sending it back to the store.
