Justine and I both have Gmail accounts, so that part was easy. You simply create a document in Google Docs and share that document with your partner. You can now update this document over and over for new lists whenever you need them (and even access the revision history to see what your shopping lists looked like last month).
You can now access that document on any mobile device in read-only format (presumably while you’re walking down the aisles in a grocery store).
So a simple phone call while I’m at work “Honey, I updated the list” is all I need to know exactly what she wants me to bring home from the grocery store.
I find technology fascinating when it intersects with everyday life to make things a bit easier.
Do you have any technology tricks like this? Feel free to share them in the comments.
