Dell Studio XPS 13, and now it's popped up on the company's website -- sort of. It's currently showing among its laptop lineup, but trying to get to the individual product page gives us an error screen. Starting price is $1,406, sandwiched just between the XPS M1330 and M1730. We think it's safe to say we'll be seeing the official launch soon.
