I bought an Incase Icon laptop backpack in 2005 (I think) in college. Lasted me through daily use in college for 3 years, a year of teaching English abroad where I used it as my daily work purse/carryall, traveled to maybe 7 different countries with it as my carryon/daily use bag, then a few years later my husband took over and used it daily as his work bag for a few years. In total about 15 years of daily use and it still looks brand new.
