First and foremost let me say that I know this is a iPhone forum. I thought I share my thoughts on Windows Phone 7. The reason I sold my iPhone 4 was in anticipation of the release of iPhone 5. I figured I sell my iPhone 4 now(which I did for $470 roughly) before it lost more value with the new iPhone 5 release imminent. I needed a smartphone to hold me over during the transition and thought I try a Windows Phone 7 since there has been lots of of buzz about the new Mango update. Also I will say that I've been using the iPhone OS since 3.0 first with an iPhone 1G, and the last year with an iPhone 4. I really liked my iPhone 1G and absolutely loved my iPhone 4. However this being said, no matter how much I liked my phone, I just had an itch to try a different OS/Smartphone. I have played around with an Android but never owned, and thought it was just not good or fluid. Again, I been paying close attention to Windows Phone 7, but would not trade-in given the lack of features initially. Like everyone I was ready to get a new iPhone 5 in June but, it never came. Finally with iPhone a few weeks away I figured I play out my curiosity and try a Windows Phone 7 since there has been an update that addressed it's shortcomings. So I was able to purchase a Samsung Focus for $160 which in my opinion was a steal. It came with a NODO build which added many features such as the biggest I could not live without, copy and paste. I've had the phone for about a week which I ran NODO. I'll just go ahead and provide quick summary: -UI The user interface is a nice change of pace from the grid icon layout. The OS runs smooth and is responsive just like my iPhone 4. The Metro is quite intuitive given the limitations of screen size and works well. The live tiles are nice however there are not too many apps that utilize this function and often don't work. This is to be fixed with Mango release which provides better API. OS goes without saying is breathe of fresh air. There is nothing there that I miss coming from iOS other than SBsettings which does not come with iOS standard. -Display Display is simply stunning! I'm coming from an iPhone 4 and still was surprised how rich the colors looked. It's not as sharp as the iPhone 4 retina display but that's a tradeoff which in my opinion only matters when you're reading text like on forums such as these. The super amoled is rich and colorful which has garnered many compliments and interest in public. -Apps/Marketplace Apps is somewhat of a mixed bag. Some apps like a 3rd party Youtube by Liveworm just shows what kind of apps can be developed on this OS and tools. Most of the vital apps I used on iOS 4 are there but with time and popularity hopefully this will improve. Again, there isn't one important app that's missing on my WP7. Obviously iOS has a huge advantage in this department if you rely on a variety of apps. -Games I haven't really played any games since I hardly played any games on my iPhone 1 or 4. Obviously if games your thing, then here the selection is quite lackluster. -Hardware/Camera/Battery/Memory Hardware on this Samsung focus is nice but not great. What sells this phone is the Super AMOLED display and thinness. The phone is much lighter than iPhone which has it's tradeoffs. I can't really critique the camera, but taken a few photos it doesn't compare to iPhone 4 camera. Maybe I'm being critical but I was spoiled with iPhone 4 being able to snap photos rapidly and pick a good one from the bunch. Probably my biggest issue with this phone since I tend to take lots of pictures. Battery is comparable to the iPhone 4. But again this another tradeoff since I was able to pickup two spare batteries with charger for $15 and now never have to worry about my phone being without power. This especially useful taken trips and having three charged batteries at your disposal. Honestly this part I really like about this device. Memory is unacceptable. This phone only came with 8GB however, one is able to expand the memory. But this has been a mess when expanding memory given the OS is very picky about Microsd. I'm use to 32GB, can live with 16GB, but 8GB is simply not enough. -Music This is probably my favorite feature of the phone. Zune playback is awesome. I love that you can switch songs by just swiping which is great. The killer feature for me on this is being able to just tap a letter or number and being able to quickly jump song, playlist, album or artist. Again I can't stress how great this feature is when you are sorting through 20-25GB of music. The Zune player blows my old iPhone 4 player interface out of the water. My only critiques and hopeful update coming soon, are gapless playback and scrubbing to quickly jump from long songs. Either way the Zune UI is much better than the old iPhone 4 player. Syncing is quick and easy which is great when just wanting to add a couple of songs and not wait an eternity to sync iTunes. That being said recently installed Mango RTM. I will play with the phone a little longer and provide more feedback. However the IE 9 browser which is an update in Mango is lightning fast. First impressions, is that this things makes my iPhone 4 seem slow. Again, I'll go ahead and answer some questions. I'll try to critique more features and functions.
