Well you've not got long to wait by the sound of it! :)
I like Archos, but I would dismiss their efforts straight away personally. Their screens are resistive and ‘mushy’.
Been reading about the Asus ones, and the EP121 sounds great! A tablet which can be a laptop or a desktop with the right dock. Awesome! Might be just what I need to replace my netbook.
The Android tablets won't come into their own until Android 3.0, which will have true support for higher resolutions. Once that happens I will be very tempted, especially if there is full Marketplace support, until then I would go for a W7 based one… if I was actually looking for one, which I'm not :)
