So my recommendation: Those who work professionally with the unit, should take the successor. Who max. 5 hours day what-so-ever-do-willing, will be "400 and" delighted with the Surface Pro.
Addendum after 1 year: Basically, I am still happy. Disadvantages of the unit, I noticed that if you carry around a few other things in his pocket or backpack, then 1 kg is already annoying. I also have to say that the available apps are to use really nowhere. In App Store's only garbage which has only simple functions or advertising involves OR is flawed. I z. B. a satisfactory app found to display photos. I use the supplied app, but - if you enlarge an image and then reduced again - then a "rausschmeißt" so that you are in the images suddenly upper directory - annoying. Even Adobe Reader in the touchscreen version is scrap because it has hardly functionality. One has z. B. a snapshot tool to herauszufotografieren from the PDF something. A functioning e-mail program I have not found and therefore use the ordinary Thunderbird for desktop PCs. So who wants intuitive, modern user interfaces, an Android or Apple tablet should buy!
