Firefox, great web-browsing, quick easy, nice tab feature too, however not all pages run correctly i.e not supported yet. Need to have IE on the "quick launch" bar for these sites. Open source, niece bunch of plugins as well.Firefox is my 1st choice, buy sadly only to run inline with IE.
Dell is a solid make, the wide screen is great for DVD's ect.. but some programes look very strange on a wide screen monitor. Which ever one you buy remember lots of ram is important for laptops, high speed processor, and Dell offer ver good onsite engineer support. Well worth the money, nothing worse than having to send your laptop back to Dell to be fixed.
