Hey friends, I am working on a new laptop for work which I will need to crunch numbers very nicely as my firm does a lot of applied math. I wondered if any of you would suggest the latest specs for the machine. What version of Dell is best? I am probably assuming a 2ghz+ chip and at least 512MB ram for starters. I also would ideally like feedback on how people like their Dell laptops and what is the best screen as I will be doing a lot of slide shows. Any comments, Dell feedback or suggestions are greatly appreciated. Thanks!
