a little bit of advice but not really much help. Obviously you have a maximum price you are willing to pay - do not go over. With a laptop it is quite difficult to upgrade it apart from ram. Make sure whichever model you go for has everything you think you are going to want for the forseeable future as you will not be able to alter it. A further thought is to see what pca advise in their reveiw section towards the back of the mag. If you are getting 4GB of ram make sure the software supplied is the 64bit version as I am told even vista 32bit has problems using more than 3GB efficiently.
