Dropbox has been the reigning king of cloud storage and syncing for a few years now, but the competition is getting intense. LogMeIn, which is best known for its remote access apps, has just launched a cloud storage solution of its own called Cubby. Not only does Cubby come with 5GB of free storage to Dropbox's 2GB, but it also implements a peer-to-peer sharing system that will help you get around that limit.
Dropbox requires you to specify a single folder on your desktop to be the synced folder. Cubby, however, takes a page from other apps like SugarSync and lets you choose multiple folders and designate them as "Cubbys." The 5GB limit applies only to what is stored in the cloud at any given time.
