Your specs are all but identical to my 5600 (you have the integrated wireless and camera). RedHat works beautifully for me.
It's interesting to see how even among the cutting and bleeding edgers, there are distinctions about which distros are more cool / powerful /etc. I sense a fair amount of disdain for RH, for example.
However, I use RH primarily because I work for a company that develops commercial software for Linux and, 5 years ago, we happened to choose RH (for commercial distribution where you have to train people, etc., it was an easy choice back then). That said, I *love* it. Yes, I like the eye candy :-) though I use the prompt to do just about everything.
If you're looking at RH, it seems to work wonderfully for me and my Sager.
