Yeah the Wiimote is a gimick, yeah the Wii is weak compared to the 360 and PS3. No the Wii isn't a piece of crap. The quality of the games have been steadily increasing over the last few months (in my opinion) and lots of games have started allowing people to control it without the WiiMote, such as Mario Kart and I believe Smash Bros.
To the people complaining about the WiiMote's lack of realism I'll say this: get over it. It's a gaming peripheral, even if it was 100% accurate (and if it was, someone would be very rich by now) it just wouldn't work for games. Take Zelda, if it followed your movement exactly for sword swinging, and you got blocked by an enemy, how would it compensate for the deflection? Maybe attach ropes to the player so they get pulled back in a realistic fashion? It's supposed to be fun, and in some cases, it is. In others, it isn't, simple solution: don't buy crap games, and they might stop making them.
I like the Wii, a lot of people do, and just as many hate it, Nintendo doesn't care, they'll continue flying to conferences in their private jets lighting their expensive cuban cigars with one of the many bank notes they have lining their pockets
