Will this laptop be right for me?

Well first off, any laptop will only last for a maximum of four years. I know people will say they've had theirs for 10 years but for what you want, unless your a computer geek, which you obviously are not, it will only last 3,4 maybe 5 years. If yhou need 6 or 7 years out of it check out a desktop. But dell's are made to high quality standards, have one of the top warranty programs out there and the computer will definatley be able to handle your tasks. The only thing, youre going to kick yourself in the a$s if you stick with the wireless card you posted. Get a wireless n, in 2 years wireless g will be totally phased out. Wireless N is the fastest longest range and most reliable wireless internet option. I would also upgrade to the 6-cell battery which will give you a much longer life on a single charge. Other than that it looks good for you
