This is a Windows phone, smallish but full of features especially if you require seamless integration with the office. The OS is slick and runs fast and smoothly and applications likewise. For work this is ideal. Physically the phone is strong and reliable. It's actually machined out of a solid block of alloy so its pretty crush resistant. Battery life is long and controls are sensibly located and easy to use. Photography is very good though no front facing camera. All in all a good 'work' phone.
