Stephanie Hedge, writing for GradHacker and ProfHacker, has some excellent recommendations for working on the go.
Some of the tools she recommends are favorites of mine.
"In my opinion, Dropbox is unbeatable as the best place for data storage. It creates a local file on your desktop, and auto-syncs everything you do to the cloud. Your files can be accessed through the Dropbox website or through the Dropbox app, which is available for iOS and Android."
"My pick for best bookmarking (and notetaking!) application is Evernote, which allows you to save webpages as well as images and notes, and is the best way to sync your notes across devices. Evernote is supported on nearly every computer, tablet, and phone, and is a must-have for working on the go."
She also mentions some tools I haven't used, but now want to try.
"Wunderlist is my pick for best To Do list app; it is simple, easy to navigate, auto-syncs between my devices, and sends me emails when tasks are overdue. It also allows me to see tasks that I have completed, which helps to keep me motivated, and Wunderlist is available for Windows, OSX, Linux and Android."
Finally, she's got hardware recommendations for tablet users.
"Targus Keyboard and Case: Although your tablet will have an on screen keyboard, typing is much easier and faster when using a bluetooth keyboard. I prefer the Targus all in one keyboard and case for iPad; although pricey, it allows you to rotate the iPad in the stand for maximum workflow customization, and the case is durable but elegant. Targus also has a number of cases for all tablet and e-reader brands.
Jot Classic Stylus: A stylus is always useful for navigation, note taking, and annotating, and the Jot is a precision stylus that mimics the feel of a pen. The Jot uses a precision disc for ballpoint accuracy, and using one on your tablet is like using a pen to write. There are fancier Jot brands with far more features to explore, but for the money, the Jot Classic is my pick for best stylus. Targusalso makes a stylus that works across any device with a touch screen, although it does not have the precision tip."
