Just bought a house 12/31/11! Right at the bottom of the housing fall, so I got a pretty good price for a nice neighborhood.
Just me, my wife, dog and cat. It's a big place too so hopefully the guest room will be for a little one in the future. Until then it was either with my parents (their place is huge with a "mother-in-law" above the garage that my wife and I lived in) or the condo we rented until our neighbors above us flooded us out and then the owner of the condo decided to sell the place.
So I don't see too much shame living with your parents, hell I was just last year when I was 27.
Let's you save up some money, nice home cooked meals now and then and no need to worry about bad roommates!
Though I will admit I miss my old condo since I could walk to work from there, now I sit in traffic for 40~60 minutes each direction everyday.
