My husband asked me to figure out the best cloud storage for him to share Excel spreadsheets and pictures with his work colleagues. We already use Dropbox for our personal finance forms etc, and so I don't think we could use our free Dropbox account and make it where part of it was public, and part private. (At least I don't think we can.) Can anyone recommend another good sharing storage account and while you're at it, what is the best (and cheapest) way to get Excel? I don't know if there's a free version floating out there or not. Up to this point, we've used our Ipad's Numbers, but his new job requires Excel. I'm hoping to drop as little money on it as possible. Thanks!
