Actually, I don't think Apple sues nearly as much as folks think. I wouldn't doubt that they send a lot of threatening letters, but there's a problem with suing, and not winning.

In the first scenario, they have to actually go fight the person that said "OK", or they lose any real power with their threats
In the second scenario, they lose power. As a matter of fact, the person picked on may beat them bad enough that they become the new playground king.
The first scenario is what happens if a company files to frequently. That's why most companies will instead send threatening letters.
The second scenario is what happens when a company files, is taken up on it, then looses very publicly (as what happened to Apple when they filed their "look and feel" lawsuit). A loss such as that means not only did the original defendent win, all of the guys that were afraid of the bully are now much braver.
I don't think there's much chance at all of Apple suing HP over the look of the TouchPad, though HP might actually welcome such a lawsuit. It would give them a lot of publicity on how the TP is not only different, but better than the iPad.
