Did you end up purchasing this bag? How do you like it? Does it fit in the carry-on?

I was thinking of purchasing a Transcend. I couldn't decide on the 20" or the 22". My concern was what others said about it not really being a carry-on. I don't fly that much, about 8 times a year. However, I noticed they changed model numbers and have discontinued some of the ones mentioned previously as being too big. I'd like to get the biggest bag I can get, that will be a carry-on. So the 20" expandable, or the 22" expandable. I don't feel like spending extra for Baseline as I don't travel as much.
