I use for 2 yrs. For an mid range phone it can do many thing on phone that can be done on laptops. For e.g- Office it can be done on my phone share it on big screen by microsoft apps its appealing and keep my work done. It has superb camera with such cool apps by microsoft that enhance your cameras experince. It can play high graphic games without any utter or hiccup.
But some games that are not completely degin for lumia may not response god but and store dose not update new games that are are launched quite a time ago on andrion and ios but some game I like to talk about that are halo, mirror edge are available on iphone and microsoft. Touch response is great. New update that are impressive. Cortona is awesome it easily beat Google talk and competitive to siri. And many thing that can make you happy. Its worthy investment and happy investment.
