I was skeptical on buying Windows Phone first, but then every review I read on sites was praising it like it was the best thing in the world, and anyone who says something negative gets bashed by Windows Phone fans. As for me I have used Windows Mobile 6.x, Symbian S60 & S90, Android JB (current), iOS 6 (current). Let me start by saying that Android for me is still the best OS in the market, it's simple for a normal user while can be tweaked beyond limit for an advanced user according to one's need. iOS while pretty limited still has best quality apps and best games are still iOS only or come to iOS first. Now Windows Phone is a has a strange dilemma, it wants to be like Android by supporting various devices from different manufacturers while it wants to mimic iOS in terms of less fragmentation by limiting the specs and features. And because of this sole reason it is failing to capture both sides. By limiting the customizability and hardware support Microsoft has limited the manufacturers ability to differentiate themselves from one another in the market, while allowing Nokia to add custom features is also adding the fragmentation to the WP market. Also the dead WP7 is nothing but fragmentation. This makes MS position really difficult neither it can compete with Android for it's customizability nor the integration and less fragmentation of iOS.
Now coming onto the looks of the OS, I agree it looks better in personal then in pictures. But still nothing much to write about, I still prefer the Android which can be customized to one's liking. The much hyped live-tiles are nothing but dumbed down widgets of Android. As for the performance although this device is not the most powerful device, but still it boasts of pretty decent hardware Dual-core Krait and 512 MB RAM with Adreno 305. I can still notice a small lag when I click an application in the Start Screen even when phone was brand new with up-to-date OS and no extra apps installed. As far as apps are concerned no prizes for guessing, very few apps exist. Most big apps are either missing, out-dated, or developed by Microsoft themselves or by some unknown third-party developers. Most basic features taken for granted in others OSs are missing. One of the most irritating thing I noticed was that it instantly dropped WiFi and canceled all downloads from Windows app store as soon as screen locked out.
Everything aside, I can't blame Nokia here much, they managed to give decent hardware specs at a very affordable price. This phone shares design cues from it's bigger Lumia brothers. But this is not a unibody design and back covers are interchangeable. I do hate how difficult it is to open the back cover as there is no latch or switch to make cover lose but you need to take it off from every corner slowly to avoid scratching the screen till it comes off. The screen is average and has no Gorilla Glass, plus it attracts a lots of finger marks.
In the end this is a really good phone which is let down by an average OS.
I would recommend it less tech-savvy people who don't need much features from their smartphone, and someone who is upgrading feature phone for first time and does not want to be intimated by the features of Android and does not want to spend more money on iPhone.
