Americans love things that are either obnoxiously huge or unusually tiny. On the same menu at Jack 'n The Box, you can order an Ultimate Cheeseburger, which is fucking huge, or you can get an order of Mini-Sirloin Burgers, which are cute, bite sized. Whens the last time you went to a restaurant that didn't offer "sliders?" Do you remember when having a huge ass boom box was the baddest thing ever? Now, the smaller your iPod gets, the cooler you are. Obviously, as technology advances, we're able to get more power out of our gadgets and they now take up less space, which is a good thing. But, in general, if you take something huge and make it small (or vice versa) you'll have a hit. Mini-Coopers, I suppose, are popular, or, at least as popular as Hummers were in the 90's. As long as you can create a novelty factor with the size of your product, you'll be able to convince a nice chunk of consumers to buy what you're selling.
