While I did enjoy playing through Fallout 1 just several weeks ago myself, I got to disagree with most of your points. Like bpops said some things are rather annoying, most notably the companions and clickety inventory and trading.
I also didn't think the storyline was too great. The setting definitely is and especially how unique it is. But in comparison I especially disliked the whole Super Mutants and Master thingie a bit. Well, I also just expected something else, something more realistic and not so "fantastic".
My biggest concern though, were the ending's of Fallout 1 and 2 alike. From all I've heard about the games beforehand I thought I was to expect something really, really great, but was rather disappointed afterwards. You are only told about the towns and folks in a very general way. You hardly get any details about individuals and what you were told about the rest was rather sparse, as well. Yes, you are told about the consequences of your actions, but only in one or two sentences and a static image per town, just a minute before the credits roll. At least I didn't really get a connection to these little final stories.
Don't get me wrong, I enjoyed playing these two Fallouts and I think they are very good games, especially Fallout 2. But all the hype and cult surrounding it made those really look a lot better than they actually are in my opinion. I guess part of this hype is how unfortunately unique they are, though, how rarely games are this very open-ended.
Lastly, I am seemingly one of those fortunate guys who were granted the ability to have fun with mostly any Fallout game, as I am presently having great fun playing through Fallout 3 and I think I'm also going to enjoy playing Fallout Tactics some time in the future :)
