The online storage market is evolving fast. In the past, users could expect no more than a simple service where files could be slowly uploaded and downloaded from a mapped virtual drive or a simple web based interface. Little competition (and the bursting of the bubble) led to very high prices for a minimal amount of storage.
Over the last year a slew of new services have launched (some are launching in February) with serious web 2.0 features, reasonable pricing (including free unlimited storage) and, in at least one case (OmniDrive), the ability to read/write directly to the file with local applications like Office, on the remote server. This last feature speeds the process of writing to files significantly by skipping the requirement to download the file to the hard drive first.
