The biggest mistake was allowing apple to say: "tablets are expensive" and going along with it.
NEW CAMPAIGN: Tablets are cheap - throw away - gadgets
You need to go to grocery stores - and airlines and other high traffic/end stores and get them to under write - your already - sell below cost - model. PS we all know this wont be the case as you just WONT CHARGE FOR WINDOWS = not that expensive.
If Polaroid can sell an 8 inch android tablet for 99 dollars at canadian tire - then if it was sold at cost - it would be 50 dollars. if it was under written by canadiantire - to give to their customers - it would cost 30 dollars. for any purchase over 200 dollars - canadiantire could give away to EVERY customer - a CUSTOMIZED and branded tablet (surface) - an embedded store website / specials / flyer - that lights up - and updates DAILY. Canadiantire start screen is locked - but after 5min - you can use the rest of the machine (hey - you got it for free remember?)
Maybe this is what you could do with Really Terrible version
White label - co-sponsorship idea aside - for the rest of us - prices above - full windows.
