It's silly to declare "I will definitely never buy this console, no matter what," when there's no telling what the future holds. Sure, the 3DS doesn't have any games that interest me now, but am I really going to say I won't buy one three years from now when I have no idea what's going to be out then?
Hell, the PS3 was completely worthless before 2008/2009 or so, and now it's by far the best console on the market, and most of the people I know who (foolishly) declared back in 2007/2008 that they would absolutely never buy one have bought one since then. >_>
