I am 27, and I really love them and have considered purchasing one, but I wouldn't feel comfortable carrying it around. I would like a makeup bag or wallet though, and would use that...or one of the cute vinyl figurines for my desk.
Like Innocence said, Notte and Biano are great patters to use, since they are solid colors. Other solid colors you can consider are Fuma and Arancia, which are grey and orange respectively.
Also if you're looking for a pattern, I'd like to suggest Tutti. I think Tutti looks great on the Zucca.
