With the rise of high-speed external peripheral connectors such as USB 3.0 and Thunderbolt, internal upgrade options are not as critical as they once were, but they still make a difference for some components such as the graphics processor.

All-In-Ones vs. Laptops

The all-in-one is smaller than a desktop, but it still is tethered to a desktop space. Laptops, conversely, move between locations and supply power through their battery packs. This portability makes them more flexible than the all-in-one.

Because many all-in-one PCs use all the same components as laptops, the performance levels are mostly identical between the two types of computers. The only advantage that an all-in-one PC might hold is the size of the screen. While all-in-one PCs generally come with screen sizes between 20 and 27 inches, laptops are still generally restricted to 17-inch and smaller displays.

All-in-one systems used to be less expensive than laptops, but with technological advancements, the tables are now almost turned. You'll find many laptop computers for less than $500 while the typical all-in-one system now costs roughly $750 or more
