I've sat in 10A on a HNL-BNE flight. The legroom isn't unlimited, but it's certainly better than most other economy seats. You're at a bulkhead, so nobody can recline into you. And I found that I was about to get up out of the window seat (just) without the people in 10B or 10C needing to get up.
I've flying on that route in a few months and have already paid for 10C based on that previous experience.
