The clamshell will be a great platform to try os x and makes a great mobile communications machine. Max the ram with a single 512 chip as it only has one slot. It will also benefit from a larger faster hard drive. 5400 rpm and as big as you can afford. It may have the 127 gb limit on the hard drive though I am not sure. It also needs wireless card if it does not already have one. As the original card is pricey you may want to check out the guides on this site for using third party cards. Have fun!
