Need to share files between your home PC and your laptop? Â There are plenty of ways to do it, but two of the easiest are Dropbox and Cubby (Google Drive is very similar). Â Both sync files between your PCs and their cloud storage (up to 5GB is free, more if you’re willing to pay). Â Cubby is new, and still invitation only (you can sign up on their site to get an invitation someday, or ask me for one today); Cubby does have an additional feature that Dropbox doesn’t have: while you can sync 5GB of data by going through their cloud storage, you can also sync unlimited data directly between your own PCs.
(Full disclosure: that Dropbox link is a referral link, if you click it we both get more free space; and if you ask me for a Cubby invitation that will get me more free space too.)
Update: Cubby closed down in 2016.
