I will be taking my laptop in December. I plan to put it in my carry on backpack duffle do-hickey bag, and still be able to take another small carry-on, so space isn't an issue. We can watch videos on the plane- We have 3- 3 hour flights, so usually no movies. We can recharge in the airports between flights. Travelling with a 4 yr old, that can be a make or break situation for that long of a day. Being able to get online once we are there is very advantageous to look stuff up! I also unfortunately need to keep in touch with work, and with our housesitter as we'll have no phone service.
The only con is having to get it all out for inspection, but that will only be once on the way there and once on the way back.
We used this list for our recent trip. It was very helpful. We found once in Aruba we had taken way too many clothes. Things we could not have done without were lots of sunscreen, refillable water bottles for use on the beach and our hats.
