I choose to not care so much, based on who the parties are.

There is more to life than whether one giant company is suing another giant company. I would care a lot more if Apple used their patents to squash small competitors, but they don't. This is purely a clash of the titans.

I use Apple computers because they are the best computers for me to get my job done. Patent suits don't change that. I use Google search for the same reason.
