After very annoying experience with Android and its certainly good reason not intuitively designed configuration I felt at Windows 8 rather quickly at home and could without great read in manuals complete the facility during use.

Here, then, an American company has built the fruitful cooperation with the secret services, and if you're not prepared exclusively American companies to acquire programs surcharge, of which certainly no or at least no credible statements about the data security are made equally good reason, is it can not be used for business, you will not violate German law.
With a heavy heart I also sent back the unit and search now continues for a solution. However, if you play anyway with "Whatsapp" and similar childishness around, can confidently Syndicate data via the cloud. The device itself is quite recommendable.
