It looks like the launch of Kid Icarus:Uprising will be accompanied by a plastic stand so that you don’t have to hold your 3DS while you are playing it. While the controls of the new Kid Icarus might be frustrating or tiring to the hands Nintendo felt that they would give 3DS owners a break by letting them sit it down on a table, that is if you have a table while you are sitting on the bus playing your handheld system. The stand does not make much sense now but maybe it’s uses will be more apparent later on…

As a 3DS owner myself let me be the first (OK probably not the first) to say “WTF?!”.
I don’t see any use for this what so ever, the screens are too small to want standing on a desk in front of you and the device isn’t that heavy, if your arms are aching you have been playing too long or need to hit the gym.
