Jay these look perfect in some ways, but I like the laptop on the boat: 
gives me something to do while crusing between landfalls. Now on a hike!!!

Cheers

Alastair,
Get a couple of these for trips, and do not take the laptop:

http://www.hyperdrive.com/

I have the Colorspace model, with the 2.2" screen, and it is fast &
reliable. When the hard drive is full, just replace the drive, and put away
the original as a permanent backup.

Cheers
Jayanand
