Evernote

If you have any kind of Android device, I recommend you try out the Evernote app. It is also an app available on Google Chrome, and what it does is connect your PC or Mac (I think) to your Android device using a notepad-type application. You can type on your computer and stick it into a note on Evernote and then pick it back up in your Android device. You can type something up on your Android and then get it onto your computer too.

I use Ever to take notes for my book reviews while I am using the Kindle app to read books. I can jot down thoughts while I read so I can refer to them later for the review. I can also use it to jot a quick note about any writing ideas I have so that I can leave the laptop closed.

The website, where you can access any of your notes on any browser is https://www.evernote.com/
