That's clearly a marketing-based, gimmicky success on Nintendo's part. The trend is typically that people buy a wii and let it sit on their shelf and only play it when they have a lot of people over. The 360 and PS3s are far better gaming system for people that actually care about games. The Wii is a revolutionary system that you can certainly have fun with. It just doesn't compare when it comes to your traditional gamer.
That said, the DS embarrasses all three of the next-gen consoles. It looks good, and for the first time in Nintendo's history it feels closer to a mobile phone for adults than a gameboy for children. It has the widest variety of games of any current platform (even edging out the PS2), and it has the most games that make you go *wow*. I'd go so far as to say that if you care about hardware, get a 360 or PS3, but if you care about games, get a DS.
The DS has everything:
hardcore retro eye-of-the-beholder dungeon crawl (Etrian Odyssey),
nethack (Izuna, Pokemon Mystery Dungeon),
rhythm games (Guitar Hero, Ouendan),
platformers (Sonic Rush, Mario 64, Yoshi's Island),
Tony Hawk (American Skateland is a truly faithful port, except that they made the game not suck)
Harvest-moon and descendents (Lost in Blue),
Turn-based wargames (Advance Wars, Panzer Tactics, (and if it ever gets an English release, the daddy: Dai Senryaku)),
Stylus games (Trauma Center, Cooking mama),
RPGs (Final Fantasy, Magical Starsign)
Puzzle games (Puzzle quest, Planet Puzzle League, PuchiPuchiVirus, Mr Driller)
FPS (Metroid)
God games (Sim City, A.1701)
Virtual pets (Nintendogs, and all its god-awful clones)
Edutainment (Brain Training, and all its god-awful clones)
Multiplayer arcade (Mario kart, Bomberman)
2d fighter (Jump Stars, Guilty Gear DS)
Adventure (Touch Detective, Phoenix Wright)
Every one of the big consoles specialises around a few genres; for example, the 360 has no good turn-based strategy games or dungeon crawlers. But the DS has a bit of everything; there is no genre you can think of where the DS doesn't have at least one good game. If you had to pick just one console, get a DS.
Worldwide, the DS has outsold all three of the TV-consoles put together (if you consider the big four in America only, it's merely got the top spot at 44 percent market share. (Wii and 350 each have ~17 percent)). That Nintendo makes a profit on both the hardware and the software is just the icing on the cake as far as they're concerned.
