ok, so i'm contemplating spending money on a wii and either fit or active (mostly because of people on here saying how good it is).

but. we're saving for a deposit and such and being one of those idiot financial-martyrs, i'm thinking it's not worth it just for me -- except i'm not likely to join a gym (too expensive, and i'm too shy) and it's just way too f'ing cold to walk much, even if there was time before work, or it wasnt pitch-black after work.

is it a worthwhile purchase? or is it more like the ab-rocker that ends up in the box under the stairs for all its life?
