I try to pack light, but for me, light is a relative term. My travel is pretty much entirely leisure travel, and I end up with my carry-on rollerboard is an electronics bag. There's no room to try to pack clothes in there to use that as my only bag. I do try to keep things down to 1 checked bag these days, although my upcoming trip this summer is going to test that, especially when it comes to my wife. Couple weeks, with multiple climatic zones being traversed.
