1- Chumby with the 8 inch screen. (The 3.5 inch might work, but have not tried it.)
1- Keyboard for the Chumby
1- Usb memory stick (128 meg is perfect.) (preferably empty)
1- Computer (for downloading and expanding the software)
1- Wifi router or access point connected to the internet or an intranet (self contained network not attached to the internet.)
I have no connection with Best Buy. http://www.bestbuy.com/site/Insignia+-+Infocast+8%22+Internet+Media+Display/9854795.p?skuId=9854795&id=1218185322584
Price goes up and down on this unit. Supply vs demand I guess.
Best buy no long seems to sell this product but you could go to http://store.chumby.com/
and pay a premium.
The new Chumby8 is supposed to come with a browser at about $200 at the time of this update.
The Sony Dash, which I have no use for sells for about $150 at the time of this update. I can not confirm whether it has a real browser. We do not prefer it's user agreement. Caveat Emptor.
Update: Even the Sony Dash seems to have been pulled from the retail shelves. I am looking for an Android tablet to do a follow-up instructable.
