Years ago, in the 80s, Modern Photography did a story on a newspaper PJ who went to a Pentax 110. They showed some of his work and gave his reasons for using it. I guess given the normal size of paper prints, it was alright. Actually, some of that they showed in 8x10 was acceptable by themselves from MP reproduction in their magazine.
EDIT: I also used to know a person who fell for the 110 Pentax system, got some of the lenses and all. He had been trained as a photographer but didn't do his on processing any more. Still, he loved that camera and used it all the time.
As to developing, from time to time you can still find 110 reels on ebay or other sites. Somebody else had them for a while. I had one, but I got it with something else and never used it. Don't know if I still have it or not. I have even seen 110 film holders for Omega D5/6 enlargers. It's still out there, even if not commonly seen.
