I'm a little late to mention this but Plants Vs. Zombies is a seriously good gaming value at $20. The game is a lot of fun and has quite a variety of game modes. I'm not sure what all it's available on - I know there's a Mac version (Intel only), and I'm reasonably certain the is a PC version as well. There's also a free demo so if you have any interest in a solid little game on the computer of your choice you should definitely hit that link and check it out.
Unless it the link doesn't work where you live of course, in which case suck it up! ;-)
