Your mainstay domestic travel bag

Apps (Tripit, Facebook, etc...) Skype for International Voice

Because we access sensitive data

For those international flights or just a 1-3 day trip

2nd PC for webex and documentation on flights in cramped airline seats

for when the batteries run out

Because we carry a lot of VMware images

It's a lot better than carrying every possible power adapter with us

Because real laptops don't come with serial ports anymore.

It's big but, when you're in a 3rd world country it doesn't exactly look like you're carrying a $4000 laptop; and therefore isn't worth killing you to steal

Because you don't always have enough power outlets, especially in other countries

to play video's in your hotel room on the plasma

Because sometimes, you still need paper

to keep your expense reporting scanner safe
