This is the top of top of the line model with 8GB of RAM rather than the normal 4GB or even 2GB seen on equivalent Atom versions.
It comes from Dell Outlet and is 'Certified Refurbished'. I've bought several tablets over the years and have never seen any use on any of them. No qualms at all about buying one - currently waiting delivery, which is usually 10-14 days.
Dell Outlet delivery is currently free (until 29 May), normally £22 + VAT.
There are many other configurations available at cheaper prices (starting at £335) if this one seems overkill:http://outlet.euro.dell.com/Online/InventorySearch.aspx?c=uk&cs=ukdfh1&l=en&s=dfh&brandid=8
The full price of this one (on the main Dell site) is currently £879.

I like this Dell Tablet range and have the keyboard with battery in it to turn it into a proper laptop with incredible battery life. I also appreciate having a cellular modem built in so I have easy conectivty without Wifi. Tethering to a mobile is not as convnient, but each to their own.
