The thing that bothers me the most about the GBA isn't the size (although I do have my concerns about it...) but rather the fact that it's internal battery is irreplacable, you can't even pop in a pair of AA cells to see you through until you can get to a charger so when it fails (and it will) you'll have no recourse but to buy a new one. Nintendo cite three years before this'll happen but it'll vary depending on how many times it gets recharged. Given the amount of mistreatment they're likely to receive out here in the real world, I'm predicting they'll start failing in large numbers in less than two years.
