I've had some experience with Asus laptops and Dell laptops/desktops. In my opinion, if you want a more beast of a machine (worse battery life) go for an Asus. It'll do what you want and do it well. If not, I recommend either the Dell XPS M1330 or the Dell XPS M1530. Both are great laptops (I'm typing on the M1330 right now) and you won't be disappointed. A word of warning though. Dell make a lot of mistakes with their laptops. Your laptop is hand built according to your specifications, so obviously with that much man handling there are stuff ups here and there. Not to worry though, because you can call Dell and a technician will come to your house the next day and fix it. The major pro's I find with my M1330 is the battery life. I have a 9 cell battery (may need to buy it off ebay, don't think they sell them in Australia anymore) and with themes disabled and all the crap I don't need running, I get about five and a half hours battery life. I would say about four hours battery life with high performance on. Note that I also have really powerful specs, so even with a really powerful processor this laptop gives great battery life.
