Here's a few of my simple organization ideas:
-I bought 12x Akro-Mils containers and neatly fit almost everything I own into a small storage closet which I rent for $25/month. For anyone organizing their stuff like this, let me encourage you, it is well worth the peace of mind once you're finished.
I highly recommend these, they are the only type of bin you can stack as high as you want without the lids cracking under the weight.
-I got a portable 2Tb hard drive and put it in a hard case protector. I use a laptop and a document scanner which is about 2" thick and the width of a piece of paper to scan stuff and save it along with our typically backup (legally ripped workout DVDs and movies, legal documents, even my wife's recipes) to the drive. If I need to fax anything, I use an online fax service, and instead of printing things I just view them on the laptop... I can even open a PDF document and sign it digitally, then fax it without touching a piece of paper. So in this way, I rarely need to print anything unless it's for someone else, and if I'm the recipient of the print-out, I can just scan it and throw away or shred it.
-My wife and I share a Gmail account which syncs our google calendar and task list to both of our Android phones, which are set up identically with widgets for our google tasks, calendar, up to date weather, gmail, etc. She or I can put an item on the task list widget and it shows up on the others' phone. Pretty awesome.
I'll add more if I think of them.
