Bikes: The same GT Outpost Mountain bike I've been riding since 1996, although I modify it throughout the year for commuting, touring, and recreational riding.
I recently went through an excruciating search for commuting bags and ended up buying - then returning - several models. If you plan to take the bags off your bike every day when you get to work, don't take the type and design of mount lightly. I thought I could live with one of those bags that require a million little adjustments to stay tight, but I got totally frustrated almost immediately. Find something with a quick clip-on/clip-off mount.
