Im sure heaps of people out there must be carrying their laptops on board
when they are cruising for navigation/internet.... what is the general
consensus on life? Do they suffer a lot from corosion? is anybody opening
up their laptop and sparying the circuitboards with anything?

I have two notebooks that id like to carry permanently on a thunderbird 26,
mainly for navigation use, so they'll be on most of the time and id like
them to last at least a couple of years if possible.... I had the idea of
separating the screen and the motherboard/HDD, encasing most of it in a
waterproof container, nolting the screen to a bulkhead and using an external
keyboard.... a bit over the top?

Is anyone shockproofing their laptop, or just sitting them on a table?

Thanks all
Shaun
