All-in-one desktops coming into their own

The all-in-one computer has been one of the most significant developments in the desktop PC market in the last decade. Despite industry observers increasingly referring to the present as the "post-PC era," the need for personal computers remains, and this is one area where all-in-one technology continues to shine.

The all-in-one desktop describes a PC that, rather than a separate tower and monitor, combines these into one. The system still requires an attachable keyboard and mouse, but, similar to a laptop or tablet, greatly reduces the number of wires needed to make the PC run.

This simplicity makes the all-in-one PC much more convenient than traditional desktops, as it can be set up in more places around the home or in the office. The systems also tend to be more affordable than mobile PCs, and remove concerns about battery life.

When in the market for an all-in-one PC, it is important to know what to look for. As with traditional desktops, processing power is a key advantage of the one-in-all system. Additionally, new developments have added touchscreen technology to many all-in-one systems, expanding their utility for both work and pleasure.

According to a 2010 study from market research firm DisplaySearch, the all-in-one PC market made great strides in 2009. Between 2010 and 2015, the market is expected to experience a 13 percent compound annual growth rate, the study says.
