The following software represents my favorite productivity Apps on each of the listed operating systems over the last several months. It should be noted that some of the Apps are compatible on multiple platforms. Enjoy!

PC Software

Chrome OS

Google Docs (Free) is a great office document suite that is fantastic for collaboration. For example, multiple individuals can edit the same documents at the same time. Such documents can be shared privately between colleagues or publicly for anyone to contribute. This software is also compatible with many other office productivity suites for sharing with other applications like OpenOffice or Microsoft Office.

Linux OS

Gimp (Free) is an open source software that allows you to edit pictures. It shares many of the same features found in Adobe Photoshop or Pixelmator but does have a higher learning curve to master. Nevertheless, it has been reliable for me and is powerful enough to do everything needed for intermediate photo editing.

Mac OS X

ScreenFlow ($99) is a screen recording and video editing software. It has a very low learning curve and enables users to produce high quality videos with smooth animations and multiple layers of video. Also, this software allows users to integrate green screen effects and magnification to video clips. With all the options available, it is a much more capable software than iMovie.

Windows OS

Game Capture HD ($149 with required Elgato Capture Card peripheral) is marketed as a tool to record video games, but I use this software to record any HDMI video source. So anything on an iPad screen or another computer can be recorded in 1080p video. This has been useful for me while recording instructional videos to demonstrate Apps on other devices.

Smartphone & Tablet Software

Android

iAnnotate PDF (Free) is a very powerful PDF annotation software that is available to most android devices through the Google Play Store. I use it to mark up documents on the go with text and written annotations. My favorite feature about this software is the ability to open more than one PDF document as multiple tabs within the App. This makes it easy to compare multiple documents while working.

Fire OS

Evernote (Free) is one of the best digital note-taking Apps around. This App is great because the same content on other versions of Evernote (computer, iPad, etc.) is accessible and editable. With Box Cloud Storage file access, it is one of the best productivity Apps on the Amazon Appstore for Android.

iOS

Keynote (Free or $10 for old iPhones and iPads, purchased prior to 9/1/2013) allows you to present slides and will accept PowerPoint files. You can also annotate directly onto your slides while giving a presentation and create simple animations using the Magic Move transition. With these features, you can better demonstrate concepts with annotations and motion while presenting. If you have an iPad, I encourage you to try presenting with this App sometime.
