Then I can always bungee cord other items on top of the trunk, too.
Did the backpack thing from when I started commuting last spring until Christmas. Not a big fan. It worked for me and made commuting possible at a time when money for a rack, trunk, and/or panniers was tight, but it's certainly not my preferred method at all.
+1 on the Topeak Trunk bag with the Quick Track system. Have used a Topeak EXP bag for the last two years and it has held up remarkably well. The fold down panniers will hold a change of clothes, shoes, lunch, jacket when it gets too warm. etc. and its pretty durable. Probably not the best choice for carrying a lap top or riding in the rain, but for a quick simple way to get the backpack off your back, its hard to beat.
