Right, never thought of that, I never think of the Kindle Fire as a reader!
Incidentally, if your wife isn't too keen on the Sony because of the price, but you'd prefer to stick with what you know, what about a refurbished one? I just noticed that the
Sony Outlet store has some refurbished T1s & T2s for £80-£84. Better be quick though, they've already sold out of a few of them.
