The Queen is to join the nation's fangirl slab-fondlers, according to reports. The fabulous soaraway Sun has the story, quoting "a royal insider" as saying that the monarch was introduced to the joys of the iPad by her grandsons Princes Wills and Harry.

IIRC the two ipods were gifts (the 1st being from her grandson, the 2nd as noted in the article from Obama) so the Queen didn't purchase, she would also need to have a continual supply of stuff from Apple for at least 5 years. There is also the fact of who supplied the item, the Queen may use Nokia for instance but purchase all her mobiles from The Carphone Warehouse so TCW gets the Royal Warrant.

I think one of the big appealing things about these mobile devices is that they are easier for very non-technically minded users to use. At least easier than a desktop. The user interface on the mobile devices has a more simple domestic appliance feel to it than a desktop.
The more computing device customers the better for any of us that earn our livings supporting computing devices. :)
