You can use a remote control app to control your computer via your tablet. But if you need a more comfortable control experience, you may like to use the Sphinx docking station to turn your tablet into a desktop computer.
The Sphinx is a versatile docking station designed for iPads and Android tablets. As shown in the images, the docking station features a portable, foldable design for easy to carry with your tablet. Using its raised cradle the docking station can hold your tablet in landscape viewing mode and provide a comfortable ergonomic viewing experience, and two built-in USB ports allows it to connect your computer mouse and keyboard in order to create a comfortable desktop workstation, while in-built WiFi and Ethernet let you freely access to the Internet. The Sphinx docking station also needs its custom designed remote control app in order to remotely access your favorite softwares in your desktop computer.
At present the team of the Sphinx is raising fund at Kickstarter. Pledging $145 will let you own the docking station. If you’re interested, jump to Kickstarter official site for more details or have a look at the following demo video first.
