I agree completely with everything you said. Abed is one of my favorite tv characters, actually, I love the whole cast, they're all great. And the show did start out a little shaky, but once they got the characters down, the show just took off. I think it's the show I look forward to the most every week. I'll definitely be buying the dvds. I might even buy at full price instead of waiting for a sale less than $20.
Oh, and Abed and Troy at the end of every episode is awesome. I hope there are lots of extras on the dvd.
