With another division I get A6's which I mostly use for keeping titles and short notes of the topic on the larger A5's. And I can place them around my keyboard without comfort penalty. It is really efficient to keep short info or headers of topics under your hand all the time. I even sometimes produce A7's for shorter notes.

And for post-itish use, I prefer masking tapes. They are adhesive enough to fit many situations, and according to their real purpose, they do not leave any trace on walls, furniture and electronics. For right behind my monitors, I use A6's mostly, and with A5's on the wall, I generally use markers to write.

You guys can try any of those. And for computers, I've tried the evernote, (see at: evernote.com if you haven't) and liked it but it is more than I need really, so I do not use it. I would suggest Google keep (keep.google.com), which I'm actively using. It is fast and simple. And another great tool you can reach with your Google account is Google calendar, (www.google.com/calendar) where you can set notes with reminders and events which you can see them on calendar.
