I have 658,287 lifetime flight miles (and that's just with United Airlines) so I know quite a bit about travel. As a techie, here are my must-have travel gadgets:
Clamcase iPad Keyboard Case: When I'm not travelling, I use my iPad as a media consumption device to watch movies, play games, or keep up with the news. However, when I'm on long flights, I've found that encasing my tablet into its Clamcase Keyboard Case lets me use it to produce content. The keyboard is comfortable and gives me the ability to navigate complex spreadsheets, respond to emails, and, of course, work on my Great American Novel.
Wacom Bamboo Stylus: While the iPad is responsive enough to not need a stylus, I like to doodle in the air every now and then. So, I've found that travelling with a stylus lets me nurture my inner artist even when I'm 30,000 feet in the air.
Mophie Juice Pack: I travel with a lot of gadgets, but my phone is the one device that I can't afford to let it run out of juice. The Juice Pack functions as both a protective case and a power source for my Samsung Galaxy Android phone. The Juice Pack has allowed my phone to even survive an eight hour flight from Houston to Honolulu!
NapAnywhere: I used to use those U-shaped travel pillows, but I recently switched to NapAnywhere. It's so much better! It even makes sitting in a middle seat enjoyable! I've even been tempted to give it to the person napping next to me when their unconscious head starts slipping toward my shouldar.
Uber: This is an app that makes arranging a car safe and easy. I simply display my location and a car arrives within minutes! Since Uber stores my credit card information, I can just get out of the car at the end of the ride.
