I've never realized this was even a problem, much less the biggest one.

Yeah, my biggest issue with touch screens by far is the lack of precision. This point seems a bit silly as your fingers typically move fast enough to allow your memory to recall the image.

Maybe in games this is more of an issue, especially where you need to leave your fingers in the same position and the design of the game does a poor job of taking this into account. But those are mostly edge cases.

The problem with precision is one of visibility. In my experience, the problem us that I can't see the exact spot where the device thinks my finger is because my finger is on top of it. This is at least the case with text selection.

Could be a problem for games where your finger might obscure the thing you want to interact with.
