I hate dling games, I much prefer to have the box and the cds and the manuals. And the smell!! Beautiful. I love new game smell.
I always feel slightly grubby if I dl a game illegaly, so I bought the one I did and now just go retail.
I'd say 17" is well portable, espcecially if you're just going to move it around a-regualrly. I know sevral who carry their d900s around with them, and I plan to join the 17" carrying crowd with that new arima soon.
