Okay - I want to travel light and what I am looking for is an adapter that will:

1) give me power from the wall and let me leave my brick at home;
2) give me power on the plane;
3) also power my digitial camera so I can leave that brick at home (I'm willing to buy a special tip);
4) is small and light;
5) is more or less universal - I get a new laptop every year or so, I want an adapter that will work with whatever I get.

Any happy users out there who want to recommend their make and model?

Thanks, TJ
