You're very right my friend. And that is one of the big uncertainties for me. The first three are already proved and many forums around have the workarounds, patches and all that. While the last two are still to go out (it reminds me certain beta testing we were subject to recently...)

All the cheap tablets I'm looking are Android 2.1 (One offers 2.2, but it is true they have many bugs), which is not so bad, but we will end with the same no-flash-10.1 problem we have in our beloved N900's.

Finally, I also like the ZT180, except for the BIG size (10.1"). I don't think such big screen will be comfortable for travelling (Which is one of my big needs). It offers Android 2.1, Cortex A8 processor 1GHZ (Same than iPad) and can be found for 190$ (Including shipping) in Ebay, or 250$ (with case and 8gb SD) directly with Zenithink.us.
