If you are tall, then no amount of reclining is going to give you more space. The knees are too far forward to stretch your legs, _especially_ when the person in front of you reclines.

In other words, you are inconsiderate.

I'm unusually tall and flying has always been unpleasant no matter what. I can actually deal with the reclining because it's actually physically impossible for the person ahead of me to recline since my knees are in the way. What really gets me is the fact that the seat back only comes up to my neck and I can't sleep because my head just flops around. I've been meaning to find some security-friendly contraption that could extend the back a little bit to immobilize me a bit better.
