I bought the unit as a successor for my Surface Pro 64GB in a large electronics market. There was a special offer incl. The Type Cover at a pretty reasonable price. I had previously done already from the previous model, but it seemed to surf a little too unwieldy to work a bit too small and a bit too weak with the only 64GB of SSD (as was, for example, the refresh function of the operating system that's not possible). Finally was too puny for my professional purposes the battery with its more than 4 hours. All these drawbacks Microsoft has now fixed. I am very satisfied with the device. Unfortunately, Microsoft has had evidently inspired by other manufacturers and the unit built so that an exhausted battery can not be replaced (even by specialists or Microsoft itself). This is actually an absurdity. It means that the unit is only possible via the mains or just can not stop using in a few years. Unfortunately, Microsoft has built a glossy display. This can when working very, very disturbing. For a supposed professional device also incomprehensible. Finally, the holder for the stylus on the (optional) keyboard of a device in this price range is unworthy: It consists of a plastic strap that is self-adhesive attached to the underside of the keyboard. A bad joke. But as an overall package, the device appears zzt for my purposes. no alternative. Mainly because it is small, light and durable. Nevertheless, the device has a large display, that's okay for a notebook, really huge comes along with tablets in a positive sense. These advantages, coupled with the characteristics of a full-fledged computer, which - which distinguishes it from the countless Apple and Android Pads - just be able to run all Windows programs and a really mad fast hardware is zzt the Surface Pro for me. irreplaceable. I can do that now - after a month's use - even notice. I would buy the machine without hesitation again.
