Simplicity is the reason tablets sell well, no mouse, no keyboard, no fancy gui, just you and your fingers and an app.
My tablet came with a keyboard.
I have replaced my laptop with the tablet . I can even plug in a Hardrive or a wireless mouse and micro +normal sd cards.
It works great on web. Makes no noise, no heat and can do all my office work i do offshore "raports" etc.
Has a quadcore cpu that seem to handle all lesser tasks ok.
