I have been following the news of the Archos Tablets for a while.

This is the thread,

The Archos 43 is on preorder at Amazon for $250. which is 4.3 inches. Everything smaller than that will be too small IMHO. The 3.2-inch is already for sale at Amazon.

BTW, is your N900 a HK version? I don't have one, but I will go back to HK in 2 weeks and hopefully buy a used one if it is cheap over there but it has to be a chinese version.
