If you’re talking about Surface tablet peripherals, the discussion has to start with the Touch Cover. At just 3mm thick, the Touch Cover is incredibly thin, especially considering that in addition to protecting your Surface, it also features a fully functional touch keyboard and trackpad. The cover snaps to the Surface magnetically, and is available in Black, White, Red, Cyan, and Magenta. In our own empirical testing, we found typing easier and faster on the Type Cover (next slide), but the Touch Cover definitely beats a virtual keyboard for data entry.
