I actually agree, though for different reasons. I own probably twice as many DS games as I own for any other systems (barring perhaps PC) and I've been buying systems and games for 20 years. DS just has an excellent mix of completely wacky innovation type games, and traditional old-school style gameplay (including the rebirth of some genres I like, such as text adventures), and games I can show to my grandmother at social gatherings and catch her interest.
For that matter, DS is also well on its way to being the best-selling system of all time--you could argue it's the people's choice.
