In response to your query about taking the Mac as carry-on
luggage:

I have travelled with my stock Plus many times on airplanes.
I carry it in a soft-shell type standard carrying case.  I
usually manage to stuff it (barely) into an overhead bin;
I don't think that I've ever been able to get it under the seat.
If the steward-persons were hip, I was able to get it stored in
one of the little closets at the back or in the middle of the
plane.

I have never had any kind of problem or complaint trying to get
it on a plane.

Caveat regarding your data:   NEVER (EVER EVER!) put your
floppies through the X-ray thingie you have to walk through at
security;  they will hand examine floppies, and seem to have
gotten used to such objects passing through.  Back up your HD,
just to be safe (I've never lost data, but I've never flown
through London, and security varies from airport to airport),
and be prepared to plug your machine in and turn it on to prove
that it's not filled with plastic explosives.  

Other than that, you shouldn't have any problems.

Happy travelling !!
