With Surface RT, you give up a certain amount of flexibility in terms of what types of applications and software you can install, but what about compatibility with third-party devices? Armed with a full-size USB port, microSD card slot, and Wi-Fi and Bluetooth connectivity, Microsoft insists its Surface RT line is compatible with a large number of devices, and now you can see for yourself by visiting the company's Windows Compatibility Center.
The site lists thousands of items deemed compatible with Windows RT and products like Surface RT that run the OS. There are over 40,000 items by my count, broken down into several categories that include:
Cameras & Photo
Printers & Scanners
MP3 & Media Players
Mice, Keyboard, & Input Devices
Graphics Cards & Components
You can also search a product by name, as well as view Windows 8 and Windows 7 compatibility (notice the pull-down menu in the upper-right corner of the website). In addition, incompatible products are listed too (like the Logitech QuickCam Pro 9000 Webcam), and some are listed as having "Limited Functionality."
