Evernote needs no introduction. With Evernote, you can quickly jot down notes complete with pictures and audio clips, set reminders, or add to-do lists, all of which then sync to the cloud so that you can view them on any device.
Evernote Premium users ($5 per month or $45 per year) get offline note-taking capabilities on mobile devices, better collaboration tools, passcode locking, more upload capacity, and smarter searching. A Presentation Mode for your notes is a cool feature limited to Mac users for now.
Evernote offers mobile apps for iOS, Android, Windows Phone, and BlackBerry, as well as for Windows 8 touch devices. You can also install apps on nontouch Windows computers and Macs by way of Evernote's download page.
OneNote lets you take notes digitally as you would in a typical composition notebook, and you can create different "notebooks" for different topics. Apps are available for Android, iOS, Windows Phone (app preinstalled), and Windows 7/8/RT, and with Office Web Apps on any Mac or Linux device.
The Windows 8 app is where OneNote truly shines, not surprisingly. In addition to taking notes with embedded images and spreadsheets, you can capture anything on your Windows 8 screen using the Share Charm and add annotations to make the image meaningful. We'd like to see Microsoft include this feature in all versions of the OneNote software.
When you're on the go, having tools to connect with your colleagues--or directly to your office PC--can keep you from running aground. Although this arena sees significant competition, the following two tools offer the best feature sets--and they're free.
Now owned by Microsoft, the Skype videoconferencing and calling service is available on all major platforms, including Windows, Mac, and Linux computers and Windows Phone, Android, iOS, and BlackBerry mobile devices. Not surprisingly, Skype is deeply integrated into Windows 8.1 and 8.1 RT, and it also integrates with the People Hub on Windows Phone 8.
The thing everyone loves most about Skype is still present: Phone and video calling between Skype clients is free, and Skype users can call a mobile or landline telephone anywhere in the world for a modest per-minute fee.
TeamViewer is a free application that lets you access your Windows, Mac, or Linux computer remotely from your Android, iOS, Windows Phone, or Windows 8/RT device, provided that your main computer is powered on and has the TeamViewer app installed.
In our testing, we easily connected to our Windows and Mac machines from an iPhone, iPad, Nexus 5, and Windows 8 tablet device, and each worked fairly smoothly.
