I actually did look for TOS on TV last night, then remembered that SciFi lost the rights to CBS Drama and that's not carried by my cable provider!
I do remember watching the Animated series during summer vacation back in the mid-90's - does that count?
And I completely agree with the frontier comment. I've just caught a few minutes of an episode of Voyager and they're so pampered by comparison. All they have to do is ask the computer to do something. At least on the NX they're more hands on.
