I'm at a conference in Seville right now. I brought a Tristar as my main bag for clothing and sundries (I'll be traveling and lecturing for about a week and a bit after this conference). My conference bag is also my personal item--the Imago. It easily swallows what I need during the day--my computer, some paper, a hard copy of my presentation (the day I present), the conference program, water bottle, and miscellaneous stuff--and the Absolute Strap means it feels light and easy on the shoulder. I've also used a LCB as my conference bag--I agree that conference bags these days are tacky and often nasty--it's so much nicer to have a Tom Bihn bag instead!
