One I have to get rid here: The repair service from Amazon is just the best! After I had found a defect at the speaker output, I sent the laptop free on. Exactly seven days later I had it again, with a completely new motherboard and speakers. Throughout I could check the status of the current status. Kudos to the repair service and many, many thanks.
By the way: The tablet is exactly what I was looking for and met all my expectations
+ Tablet with keyboard docking + Digitzer + Windows8 + Battery Life> 8 hours + Performance sufficient for most applications (Office, simple CAD software, Programming, Media, Old Games)
