It was Apple's first notebook since the PowerBook 2400c without a built-in removable media drive. To conserve on space, it uses the 1.8 inch drive used in the iPod Classic instead of the typical 2.5-inch drive. It was the last Mac to use a PATA storage drive, and the only one with an Intel CPU. It was also Apple's first computer with an optional solid-state drive. The MacBook Air was the first subcompact notebook offered by Apple after the 12" PowerBook G4 discontinued in 2006. It also featured an anti-glare LED backlit TN 6-bit color panel display, a full-size keyboard, and a large trackpad that responded to multi-touch gestures such as pinching, swiping, and rotating. It featured a custom Intel Merom CPU and Intel GMA GPU which were 40% smaller than the standard chip package. The first MacBook Air was a 13.3-inch model, initially promoted as the world's thinnest notebook at 1.9 cm (0.75 in) (a previous record holder, 2005's Toshiba Portege R200, was 1.98 cm (0.78 in) high). Steve Jobs introduced the MacBook Air during Apple’s keynote address at the 2008 Macworld conference on January 15, 2008.

My general guideline is that base-level chipsets don't match well with super high-resolution displays, but more-powerful chipsets can handle denser displays with more pixels.The MacBook Air was introduced in January 2008 as a premium ultraportable with a 13.3-inch screen and a full-size keyboard, and was promoted as the world's thinnest notebook, opening a laptop category known as the ultrabook family. Here's a performance tip: if you want to use all the resolution of a super-dense screen, make sure you choose a processor and display chipset beefy enough to push all those pixels to the display. More pixels is generally better for viewing images and text. Once you've made a size decision, you'll have the tools to learn about display quality and pixel density. I'm partial to ultrawide displays, but whether you go the route of more monitors or wider monitors, the amount of display real estate does impact productivity. If you're buying a desktop monitor, screen size is also important, but you're usually choosing based on either budget or how much information you want to display. Bigger machines have room for more ports and bigger batteries, but they can weigh down your travel bag. Screen size often informs the weight and dimensions of the machine, as well. If you're buying a laptop, the size of the screen is probably the most important factor, so decide that first. We'll cover them in a future article.įor now, consider this. There are other factors relating to colors, viewing angle, and brightness you might want to factor into your buying decision, too. If you're doing a lot of high-resolution photo editing, for instance, the PPI of a 'mainstream' monitor might prove problematic when you're looking at the image on the display vs. It's worth noting that laptops often have higher PPIs than bigger monitors. PPI and pixel pitch are great ways of cutting through the confusion inherent in comparing monitor sizes, and they give you a size-independent way to compare pixel density. In other words, the smaller monitor has about 78 percent of the resolution of the larger. The 34-inch display has a pixel pitch of 0.23175 x 0.23175 mm, which calculates out to about 110 pixels per inch. The 40-inch display has a pixel pitch of 0.1815 mm x 0.1815 mm. The Dell UltraSharp U4021QW is a 40-inch display, measured from corner to corner. Even so, they are used to define the same thing – pixel density. Interestingly, pixel pitch is often described in millimeters while PPI is obviously described in inches.
If you divide an inch by the PPI, you'll get pixel pitch. PPI stands for pixels per inch: the number of pixels fit into an inch of display space.
Pixel pitch describes the size of each pixel.
