Archos announced they were working on 6 sizes from 5″ to 12″ months ago. But the issue is that Archos does not have unlimited amounts of cash to launch unlimited production of all kinds of sizes, so they can only afford to release 2 sizes for now. The idea also is for the stores not to always be out of stock like they were last year when Archos had to split their production budget among 5 different sizes, more G9 sizes may come later.

Anybody remember the ICD Vega 15 inch monster?  

So for somebody like me who has actually been using slates and tablets for about a decade, I can say that the 10 inch device is about the worst possible size.  It’s really too big to be a worthy hand held device, and it’s too small to be truly useful.  In comparison, something in the 7 inch range gives up little in on-screen utility and gains a lot in terms of in-hand usability, and something in the 12 inch range doesn’t really lose that much in terms of the in-hand experience but gains a substantial amount in usefulness.  In fact, anybody who used one of the old Toshiba Tecra M7s or the more recent Gateway effort knows that a 14 inch slate (if you can keep the weight under control), is an amazing palette of possibilities.  Go play with a Cintiq if you haven’t yet experience a grownup sized tablet.
