You know, I have to say I'm all for Nokia pursuing this. They made some major innovations in real-world technology, which they rightly hold patents for. This is exactly what the patent system is there for. These aren't just patents Nokia held for ambush; they are innovations which have literally shaped an entire industry. Nokia should by all rights be rewarded for those innovations.
I have a hard time believing that Apple disagrees. The main question, though, is "how much should Nokia be charging" for these foundational patents (which will eventually run out, but that's several lifetimes down the road in the tech sector). Apple obviously believes Nokia is demanding far too much, and so has been dragging out negotiations. Nokia is filing suit to force Apple to accept their offered licensing prices or lose the iPhone business altogether.
I'm not privy to the prices Nokia demands for their licensing deals, so I can't say if they are fair or not. I'd hazard a guess that none of the posters on this board are privy to those details - much less are knowledgeable enough about the industry to say if they are reasonable or not - either.
So, right now, I think it's best we all just stop the blind fanboyism / attack-dogism and just let the grownups decide what the right outcome should be.
