Over the years I've owned three Dell Inspirons, a Toshiba, two Gateways, a Compaq, a NEC, and a IBM.
Of those the only ones I liked and would buy again was the Toshiba and the first Gateway I had. The only reason I kept buying the Dells was because they provided financing. After all my problems with the Inspiron 8200 I'd *never* buy anything else from Dell again, including desktops and accessories. I'm sick of their support and the rules they have that keep the few good techs and customer service people they have from making you happy.
I'd cancel the Dell and take a closer look at Sager and Toshiba if I were you. If you're a member, Costco has a really tempting 17" Toshiba right now.
