When do preorders start? How have physical--not virtual--demos gone? What sort of kernel does this thing run? Who manufactures it?
Unless you have information to the contrary, the Courier, for all intents and purposes, does not exist. It's a fabulous concept--and I mean that in both connotations: fabulous in the sense that it's just a delight to behold, but also fabulous in the sense that it is "fable-like."
Continue waiting for your vaporware; I'll purchase the iPad now and the Courier if it ever comes out (and works, opposite to Microsoft's track record, as they say it does).
It is rumored that it will be out in Q3 or Q4 of this year and it will be priced around $500.
As I said I don't see any point (for myself) to buy an iPad, but if courier works as it is shown in concept I will buy it.
