The Archos 101 XS will come with its own full QWERTY keyboard. The main problems here are price and implementation.
Thanks mostly to Asus, keyboards and tablets are kind of a thing. It started with the first Transformer, continued with the Slider, and Asus hasn't really looked back since then. And why should it? The Transformer line has been very good to the company, even if the actual keyboard costs up to $150 extra (in addition to the tablet). The Slider isn't as popular, and its prices start at nearly $500.
