I finally broke down and bought my daughter a Wii, which I will, of course, also use. I must admit I was hesitant to purchase it, as the name threw me off, and I couldn't see how the control use could be fun.
I was wrong on the latter, though the former still bugs me. Not only do the Wii remotes work well, they are also fairly intuitive, though the only two games I have used them on so far are Wii Sports and Wii Sports Resort, both of which my daughter kicks my ass on regularly.
Using the remote to make Miis (something my daughter is very into) or surfing through Wii channels or the web, also gets no complaints from me, though I wish typing were easier. (You can buy a keyboard for that.) I'll soon be streaming Netflix films through it, too, which from everything I've heard also goes smoothly.
We've logged in a lot of hours already, and I suspect plenty more are to come. In all, it was an expensive investment, and I'm not sure the available Wii games are up to par (though I am curious as to what can be downloaded), but the sheer entertainment of what little we have played so far makes it money well spent.
