Go to a store and get a Toshiba. Dell suck. Their aftercare sucks and it will probably end up costing you a lot more getting it repaired than it would paying a few dollars more from a store where they actually give a damn about the customers. Do a search on line to find out about the problems with Dell.
I'm planning on buying a Dell laptop soon, so I went over to their website and customized an Inspiron 17 and a Studio 17 to have the features I wanted. In the end, the Inspiron turned out to be $700 and the Studio $900. Are there any factors that would make me want to buy the more expensive Studio over the cheaper Inspiron?
