I found a deal with Dell Outlet to purchase a 2.0 Ghz P4 Inspiron 1100 laptop with 15" display for 683 shipped. Should I hook this up? I'm planning to go to grad school soon (which requires a laptop) and I've noticed older models selling for about the same price (even used 800 mhz laptops). I need some advice ASAP as it's sitting in my cart but won't for long. THanks!
