Someone asked a similar question earlier today. I will be travelling by car across the USA in July and August and I would love to bring my MPB, which would allow me to make movies and publish my website as opposed to just posting quick recordings and photos for my blog. Can I do that^ stuff on an ipad? because I might get one. What kind of heat can MBP's take? I imagine humidity will be a big issue as well. Has anyone done this and can anyone recommend a good way to package it if I end up taking it along? I would hate to leave it behind only to find out that they are plenty durable for trips like this. I also would hate to bring it and have it get ruined by day four. Thanks all!
