Go to Japan and enter a McDonald's restaurant.
Flip out your NDS and discover that the screen has an entire mess of advertisements promoting bigger, cheaper and greasier Quarter Pounders. Too bad, a lot of spam...err, advertisements promise very similar things. Hmm.
Anyway, that's the core idea behind the "Nintendo Spot," a service that displays promotional campaigns, product information, promotional vids, demoes and digital coupons. When you're in range, the built in Wi-Fi hotspots at McDs' will allow users to check out daily McDonald's content.
For the oddest reasons, the "Nintendo Spot" will only be available for one month at participating restaurants.
