When it comes to slim, manufacturers are having a tough time beating Apple’s MacBook Air. Dell's new Air competitor, the XPS 13, may have missed the mark by a whole millimeter—but we weren't too put off. Especially since the XPS is considerably smaller otherwise, and still manages to include a 13.3 inch high definition display that looks like it's floating in midair. The insides definitely aren’t as polished or streamlined as in a MacBook Air, although they certainly look very similar—enough that you could convince us the XPS was a prototype of the Air. Perhaps a prototype from a time before repair was tossed off the list of Apple's design priorities. Clearly, repairability is still a design concern at Dell—a free service manual, and labels on nearly every screw and connector are a huge help during reassembly. When all was said and torn down, the Dell XPS 13 handily bagged a 7 out of 10 on the repairability scale.

Teardown Highlights:

• The little-mentioned webcam lives in the lower display bezel. This unusual placement allows for thinner top and side bezels. Unfortunately, it also means getting an occasional keyboard in your selfie, not to mention unflattering angles.

• We find a hodgepodge of tape, cables, and connectors inside the XPS 13's guts; the internal components are a tangle of layered bits as well. And sometimes the construction looks more than a little ridiculous. Waiter! There's a screw in my tape!

• Buyer beware: Just like in the MacBook Air, the RAM in the XPS 13 is soldered to the motherboard, and cannot be replaced. When you're picking out your new laptop, configure what you think it'll need...forever.

• Wait, did we accidentally get a MacBook display somehow? The clutch cover comes off in much the same way as on a MacBook Pro, revealing a plastic frame of antennas.

• After painstakingly cracking the display assembly clam, we find a mysterious black thread running along the inside of the top case. There's no mention in the service manual, but we're betting we just stumbled onto the easy way to get the LCD out. The thread is routed in a channel beneath the display adhesive—pulling along the side ought to slice right through and free the panel, like cutting clay off a block.
