I'm looking to buy a laptop from dell and I've narrowed it down to two notebooks, the inspiron 600m and the inspiron 8600. I'm looking for a notebook that not only is light, but fairly powerful too. Looking to spend around $1200. I like the 8600 because it has a 15" wide screen and upgradeable to a 9600 radeon mobile card. I'm afraid that this will be too heavy though I don't know which one to get.
