We (boyfriend and I) got Wii Fit and the balance board a little over a year ago--I know, because recently, when I turned on the game, it made a snarky little comment about how it had been 400-some days since the boyfriend had last used it.

That's right, we got it, he used it a handful of times, and then that was it.
I personally enjoy it as recreational exercise. I
hate exercising (unless, of course, I can do it while watching trashy television). So for me, it's really cool to have this built-in monitor that encourages your progress and keeps you on your toes about form and whatnot. And the scale is a lot more reliable than my cheap-o bathroom scale I bought at Target. Plus, the yoga poses really have increased my flexibility! Granted, it's not the same as taking a yoga class, but it's still fun and relaxing.
Good to know Wii Fit Plus has a feature where you can set up a workout and go through it without clicking around--that was my biggest complaint, too. Maybe I can swing that one of these days.
