On: Nokia perfects the clicky tactile touchscreen - iPhone gnashes teeth, swears revenge

The big question is does Nokia have a patent on this. Apple's products could really benefit from tactile feedback in my opinion.

I think the answer is "duh", but that's not likely to stop Apple. The patent situation is a Mutually Assured Destruction scenario. Nokia could likely sue Apple and get an injunction granted on the sale of iPhones. This would be devastating for Apple, but Apple could just as easily sue Nokia, and that would be equally devastating.

Neither company can afford the risk of getting an injunction granted on their products, and both companies know this.

Maybe, but there might be prior art. I remember a Popular Science article last year about some Chinese phones with this technology.
