BlackBerry maker, Research in Motion has filed a new BlackBerry patent this morning that describes keys that light up individually when you press them. Check out Russell Shaw’s blog to get more technical details. I, however, want to ask the question “Is this practical.”

On a good day I can thumb out 25 words or so per minute on my BlackBerry. I think that if each key that I hit lit up individually it would, quite frankly, annoy the hell out of me. I admit that I’ve been known to miss the forest for the tree in front of me every now and again so chime in if I am missing some obvious reason why individually lit keys are a good thing.

I just hope that if RIM does eventually implement this feature in to future BlackBerry devices it is a feature that can be turned off.

What do you think?
