I am not a recliner, so I do feel like I am losing some of my space when the person in front reclines. The pitch in F on 757s (at least with UA) is not great - I have to keep my laptop closer to me than is comfortable when the person reclines, and I do have problems retrieving items from under the seat.
That said, I don't complain because the person in front does have the right to recline, and it is just something I have to accept. As long as they are willing to go upright so I can retrieve something or get out of my seat, or accept getting bumped in the process.
