You see, a laptop owner demands everything from a computer that a desktop
owner does: reliability, performance, expandability, and ease of use. Owners
of Mac Pro or iMac desktop computers can draw the line right there because
their computers are designed for a stationary existence. But, you and I are
laptop owners. We also need that same computer to be an inch thick (or
less). We demand that it run for hours on a single battery charge. We require
that it be light as a feather. We want to conquer the coffee shop, the library,
and even a lecture hall or two!
