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.
Of course the pragmatic alternative, Microsoft, isn't exactly know for being the good behaving kid on the block either.
And mucking around with home-built PCs running some Linux distro doesn't have the same appeal to me it had 10 years ago.
So what to do?
