I'm looking at getting a notebook/laptop computer with a 2GHz Core 2 Duo processor, 1GB memory, and 17" display. I configured both a Dell XPS M1710 and a Dell Inspiron E1705 with the same specs, but the XPS was over $1000 more expensive. What does the XPS M1710 have that the Inspiron E1705 doesn't to make it worth $1000 more? Thank you.
