LogMeIn is a service that allows you to remotely access someone else's computer (with their permission and cooperation, of course) so that you can help them fix a problem. It's much easier than having them try to explain the problem over the phone, or you having to drive to their house.
Today, they are launching Cubby, a new cloud file sync, share and storage service. It's still in beta, but you can enter your email to get an invite. You can sync your files across all of your computers, tablets, and smartphones easily. You can share files and collaborate on them with others. You don't need to reorganize your files either. You can just select any folder on your device to by synced and make it accessible anywhere.
The free account is 5GB of storage. But, one of the best features of Cubby is that there is no limit to the amount of files shared between your own devices or with others. That's a big deal for a lot of people. You won't have all of those files available on their servers, but they will be shared onto all of your devices, with no memory limit.
There are also mobile apps for iOS and Android and a desktop client app to set up what folders you want "cloud enabled." There is also a "My Cubby" folder available, similar to "My Dropbox" from Dropbox or "Magic Briefcase" from SugarSync.
This is another great way to sync, share, and backup your files and the unlimited share is a really great feature.
