You may struggle finding a computer at every place you stay - i prefer to carry my own lightweight netbook. Everything Ameerat has said makes sense (law of probabilities really .... had to happen one day) 8*)

If you don't take a netbook, take a couple of decent capacity spare cards in case it's a while between computers. Aim for taking full sized images because you probably won't see those places again. When you're shooting, chances are you won't have ideal lighting because you often end up in places at midday when the sun is harsh. To overcome this, bracket your shots and play around with them when you get home. Ditto for lenses - don't carry lots of lenses - just one good one, and take lots of panos to stitch together when you get home.

Depends how long you'll be away, where you go etc etc, but if it's a while then taking a netbook gives you a spare copy of everything - one on the netbook and one on the portable HD
