What is best for use aboard. Not the glitz or lack of. NOT what is popular to the general public. BUT WHAT WORKS ON THE BOAT.
For use aboard Guenevere (27 foot that we have lived aboard for many years) we decided on the Eee PC. We got 2 of the 7 inch models when they first came out. One white for me, one pink for Jill.
The deciding factor was A. price – 2 for less $$ than one other computer. B. The navigation program and charts and radio control programs were free, not a must, but very nice. C. All of the programs (Portable Apps) fit nicely on a 8 Gig SD card that fit in them. We upgraded to 16 Gig cards, but still use them.
BEST PART, if/when one goes belly up,SD card out, pop it in the other one and it's as if noting happened.
So, as I said, for us, it's what works aboard.
