I'm not sure if I travel much lighter as my camera bag with all the lenses and SLR has now been replaced with a backpack that carries a laptop, iPod, tablet, various and sundry chargers, and a pair of noise canceling headphones. However, photo taking sessions when I get where I'm going are much lighter and easier.
I still take photos as if I'm using film. I really don't think I need room for 6000 exposures, but it's nice not to worry about running out of film part way through a vacation day - and no film stores nearby.
