On another point, I don'tthink she was the first intelligent and confident woman in a starfleet uniform. Tasha was a pretty damn confident officer and I wouldn't be so quick to say she wasn't that smart. Also, though it wasn't the winning pilot, Number One in the first TOS pilot was confident, ballsy and intelligent. On another note, Uhura developed in the films to be pretty confident perhaps even cunning.
I think my rather flawed grammar in my previous statement gave the wrong impression--a rouge "the" was accidentally inserted in a line that was meant to say "one of the first women," and I certainly had Tasha in mind what I qualified that statement.
I agree that Uhura was developed well past her TOS role in the films. I very much enjoy watching her. However, it is a challenge to get past the fact that...well, look at her uniform in the 1960s. Clearly Ms. Nichols is very intelligent and talented, and she drafted those characteristics into her character without a doubt. However, I feel a disservice is done to the earlier women in Trek because none of them actually wore pants. I mean, how can you go on an away mission in a skirt like that? Agreed that the TOS films did change this trend.
I also find it interesting that the designers of TNG tried to remedy that by creating "unisex" uniforms that were skirted, seen on both men and women in the first season (I'm not sure that even lasted the full first season). TNG not only brought in intelligent women, but actually covered them up in something amounting to a regular uniform from the start. I'm glad we saw even more of this in DS9 and Voyager, too, however I'm not sure that any uniform, no matter how conservative, would have worked to Seven of Nine's advantage in this capacity.
