Absolutely great news...I'm following this thread for quite a while and was not sure if the idea would come forward but I am totally happy to read that you might be able to deliver soon.
I would be interested for it too, incl. a keyboard with cover.

As for 3G it is a nice to have option for me but not a must, I have a Samsung Galaxy Tab 2 Wifi only and this is also ok as long as you can use tethering I'm not concerned. So count my vote as a silent yes for the majority.

Can you maybe tell how much it will cost? also for each component? Keyboard, Cover, Tablet?
