So German keyboard definitely to Windows 8.1 with Bing I think it is good and have no cons noted, come from Windows 7 and think it's good that 8ter. After I set up to say that I have discovered no useless software. Battery was half full and has loosely managed all a judge and then had even 20%. Conclusion I do not regret the purchase and am fully satisfied. Age Läppi was Acer slightly more expensive and I notice no drawbacks. Hope it helps a little further the review.
