My fiance tends to carry his lap-top bag with him everywhere, and he keeps the necessities in it (advil, kleenex, extra headphones, etc.)

I love my Victorinox bag though. It's a sling bag that looks like a miniature backpack and has an ergnomically correct swivel on the strap and a nifty cell phone pocket. My dad carried one when they went to Italy and said it was so sporty he didn't actually feel like he was carrying a purse.
