Design
The 2011 13-inch MacBook Pro is virtually identical to its predecessor. Slim with its iconic curved lid, the aluminium unibody chassis exudes premium build quality from all angles. Measuring 12.8 x 8.9 x 1 inches, and weighing 4.6 pounds, the new machine has the same dimensions as before but is a fraction heavier (0.2 pounds). Of course, the 13-inch MacBook Air (0.7 inches thick, 2.9 pounds) makes the Pro look heavy by comparison, but this 13-incher still slips into bags easily and is relatively easy to carry.
Users will also find the same black Island-style keyboard and large multitouch touchpad that have graced previous models. Chiseled from a single block of metal, the MacBook Pro feels extremely sturdy. One drawback is that the MacBook Pro's battery is not replaceable, at least not without Apple tech support. Also, the chassis can scratch easily if exposed to sharp objects, making a custom-fit cover a smart investment.
Heat
Despite its metallic construction, the MacBook Pro mainly kept its cool on our heat tests. After playing a Hulu video at full screen for 15 minutes, we measured a temperature of 90 degrees Fahrenheit at the center of the keyboard, while the notebook's underside returned the same reading. The touchpad was cooler at 80 degrees. The bottom back end of the 13-inch MacBook Pro did get toasty, logging a temperature of 109 degrees; we consider anything over 100 degrees cause for concern.
Keyboard and Touchpad
Folks familiar with the MacBook Pro know that its keyboard is one of the best around. The laptop's big square keys have a soft finish and are arranged in an island-style setup, offering plenty of spacing. They also make little sound when hit, yet provide a satisfying click. Equipped with an ambient light sensor, the keyboard is backlit as well, one of the advantages the 13-inch MacBook Pro has over the 13-inch Air.
Like MacBook Pros before it, the current version has a vast 4.1 x 3-inch touchpad that doubles as one massive button. Frankly, it's the gold standard; it let us glide our fingers across it with minimal friction and intuitively press down to make selections. We never missed the lack of a discrete mouse button, or even two.
