I bought mine and being using it heavily for a month now.Cosmetics:The nexus 4 looks beautiful, the gorilla glass 2 in the back is just superb looking. It''s slim, lightweight and you cant barely notice on your pocketconsidering it''s screen size.The border is grippy, which is good, actually a very durable device from every angle, even tho you should be careful by the simple fact that it hasglass in both sides glass is glass, call it pyrex or gorilla glass nothing is unbreakable.OS:Jelly Bean 4.2.1 is amazing, such a huge improvement over older versions I consider it nowadays superior than IOS 6.To appeal every control freak out there you need to heavily tweak to your liking, for example I consider the OS mail clientrubbish. If you need a powerful mail client do yourself a favor and buy aqua mail pro app from the playstore, going now for$4.99 In my opinion google should fire the ones responsable for the native mail client and simply hire this developer.The cpu is absolutely powerful, best in class, quad core with 2gb in ram means goodness!To sumarize, Jelly Bean is amazing and CUSTOMIZABLE which you cant really do with IOS.Problems:I actually don''t know if its a bug but my phone has trouble switching from wifi to wireless network from my carrier, sometimes it does sometimesI have to go into airplane mode for a second and back to carrier to obtain data signal.As you probably know there are several bugs reported such as problems with bluetooth, low volume for some alerts, weak vibration etc.Well it depends, some app notifications sound very loud but this probably has to do with native notifications.Anyway most of this stuff will be solved in next OS Update 4.2.2 expected soon.Desing flaws:The speaker is set in the back cover without any room left between the device and the contact surface, in other words if you leaveyour phone over the table facing up you will notice a huge decrease in the volume of your ringtones or notifications.May 27 2013 UPDATEWith the latest version of Jelly bean 4.2.2 all the bluetooth and switching through data network problems were solved.Really recommend this device.
