Touch screen computers suck if you try to use them exactly like desktop computers with a bonus input device.

If, on the other hand, you have valid use cases for using touch screen computers—or say, an entire ecosystem based around touch screen devices that are approximately the same size as a small computer screen, aka the iPad—it can be great.

That being said, I feel like the iPad and Surface already have that space covered…so they really should just be merged with the lowest tier models of laptops.
