Chromebook allows you to type papers etc.
On the other hand, a Chromebook's problem (for now) regarding the "tablet mode" lies in the ChromeOS GUI: It wasn't designed with touch screens in mind (especially the browser itself) and feels clunkier than other tablet controls. Google are on their way to remedy that through their integration of Android apps though. They're certainly not there yet, but I can imagine that changing in the forseeable future.
