Nokia built an amazing phone with customized applications and Windows Phone 8 performs flawlessly. Super fast processor, smooth video; you can finally watch a video and listen to it with Bluetooth headphones (mine is Plantronics backbeat 903+).For those skeptical regarding applications, there is Instagram and Whatsapp for W8 (download is free for both) and many more free apps, although Lumia 1520 brings a load of essential applications.Very advisable to buy a cover, not only for its protection but for a better handling. I found the device extremely slippery in my hands. I purchased a cover with kick stand, so I can eat and read or watch a video.W8 automatically backs up most your data (pics, docs and videos) to skydrive, which is very convenient. All contacts I had on my HTC HD7 (Windows phone 7.5) was imported as soon as I register my accounts (Hotmail, Facebook and Google) even without the sim card. A great feature is that you can access your Lumia 1520 from your PC as if it is an external hard drive. You can also receive and send several kinds of files via Bluetooth. The NFC (Near Field Communication)  is amazing!!I still donnot understand people who rather pay a lot more for an IPhone or Android!!I also purchased a 32Gb micro SD (you can install up to 64Gb), which is another feature Iphones don''t have.Also amazing is the battery. You will now have a phone that will keep up with you all day, provided you make a normal use of it. Remember to charge it, use it until battery runs out and charge it again, so that your battery will be optimized.Only disappointment regards to the charger which is European. Although seller sends (at no cost) an American adapter, it gets to be a very clumsy piece (both together).Well done Microsoft and Nokia.February 6th UpdateToday I test the Here Nokia (the built in GPS) I turned it on together with my car''s GPS, except that I made it work offline. Both GPSs took me from where I was to where I wanted to go flawlessly. The Here Nokia offers more detailed information and precision. I am being amazed day after day by its software.
