Over at the wonderful gCaptain blog:

While traveling to destinations around the world my setup is a black macbook (however, due to an unfortunate incident involving wine it is now the new macbook) and my iPhone. I tend towards lengthy email replies when using the Macbook so I much prefer the iPhone to make them short and quick.

On the ship my primary computer is a windows box which I need for my day job. Because of restricted permissions I rely heavily on a Portable Application Suite I launch from my waterproof USB drive and VNC to access my office computer. 

 

I work a schedule of 3 weeks at work and 3 weeks home so I get 6 months vacation per year. To facilitate this each position on the ship is filled by two people, the person on and the person off. This is nice because while at home my relief answers all emails, phone calls, ect., leaving me 100% disconnected from work. But regardless of where in the world my ship is located on the globe I must fly to it every 3 weeks. Staying connected on the road is important. To accomplish this I have set-up a custom SSH tunnel solution that I use with Apple Remote Desktop to connect back to my office network. I also have setup automatic back-ups with the Amazon S3 based app JungleDisk and use Transmit to retrieve my files. Storage is important while traveling  so I cloned my MacBook‚ hard drive using SuperDuper and replaced it with a 250gb laptop hard drive.

More at the site, including his favorite apps — a list very similar to my own. E.g., TrueCrypt is the way to secure files.

In fact, his Mac-travel, PC-work, dual-monitor & setup is quite familiar to me, though I use 37signal’s Backpack for GTD / task management, plus digital dictation and voice recognition given the volume of paperwork I create. I’m also content with FreeMind over Mind Manager for mind mapping.
