Grand Slam Tennis for the Wii: worth a look!

I bought this earlier today (with the Wii Motion Plus thingy), and it's definately worth a look.

Apart from being great fun it has a calorie tracker, so you can see how many calories you burn off while you're playing. Not exactly high-impact aerobics, but it might be of interest to some here?

And it has an online mode, so if any of you guys buy it, we can play against each other lol
