What Do You Want the Fabled Apple Tablet To Do?

It's only  a rumour,  but seems to be accepted as a given and all eyes are eagerly anticipating the Jan 26 'launch date'.

If and when it happens, what will this device do? What will it look like? For certain is it now set up be the greatest technological disappointment or phenom for the new decade.

But if you could design your tablet - what would it be like? What functions would you want? How would it work?

My take:

• It would be the size of a closed Macbook but as thin as an iPhone. 
• The screen would be about 13 inches and it would have all the function of a Macbook. 
• It would have a hard shell swivel screen cover that could double as a stand to keep the screen upright.
• A touch screen keyboard and some smart external keyboard attachment - the touch keyboard has customisable options that regulate: size, transparency, key position and function, and general interface (an iPhone interface or the iTablet interface - whatever that is).
• It would have a built in mouse - nothing more than a tiny ball or touch pad - about 1/4 the size of the pad on a Macbook.
• Some buttons would be included on the side panel but can be customised.
• Keys could have multifunction built in. Press the 2 and the @ and € also pop up a al iPhone and you can punch your option with another finger. Simples.

Love to hear your ideas.
