I don't so much mind one-song-albums as I mind one-track-albums. There's a difference there. Albums that consist of one single track are just inconvenient. And to be honest I agree with the person who said that one song albums tend to be either repetitive or when they aren't, they might as well not have been a one song album because that means the music progresses enough that it could have easily been split up into individual songs.
Someone mentioned Crimson by Edge of Sanity, which is indeed a great album, but come on, that has lots of repetition in it. It's maybe 15 minutes of material that is repeated a few times with different lyrics. I'd rather see Opeth come up with an album that is a little more diverse than that. I'm all for albums that flow together as one continuous piece of music, but with track markers inbetween so you can atleast skip around in it or just listen to one specific track if you want to.
