The Amazon Customer Service has been informed of this defect, the description of the product on the shop but still not been adapted unfortunately to this day (13:10:14). Thus customers will continue deceived.
For product: the HP Tablet Slate 10 HD 3500es makes a high impression, despite plastic housing, the screen resolution / quality is good, though not übberragend. Further functionalities have not been tested because I have returned the device immediately (I relied regarding 3G capability to the description!). The HP 10 is actually put on the market before the year round 1 and is now no longer available from HP (in stock?)
Please note that the tablet is a Spanish version, the supplied User's Manual is in Spanish. The tablet can of course also be set up in the German language.
