Nearest I have to a Tablet is me Kindle but I must admit I lean towards the theory that within a very few years PC, Laptops etc will all be replaced by Tablets.
Having spent ££££££££££££s on new laptops for boys and self in the last year I am disinclined to get a tablet until they are a little better priced and reliable. Capacity seems to be a bit of a problem.
That said Lil Bruv recently upgraded from his old cloncker to one of these all-in one PCs. Still has keyboard and mouse but everything else is built into the back and sides of the screen. Comes with touch screen but he prefers to use the keyboard and mouse. Mind you it is a 20 inch screen so I doubt if he would want to carry it around.
