Megaupload founder Kim Dotcom has been promising a big comeback through his new Mega cloud storage service. Now that it’s open to the first wave of users, we have an inkling of what that strategy shift entails. Mega is currently just a simple-to-use parking place for data with a relatively large 50GB of storage in a free tier. However, it may grow quickly: there’s promises of Google Docs-style editing, instant messaging and mobile access, among other plans. Eventual paid plans will offer considerably more storage of between 500GB for €10 per month ($13) to 4TB for €30 ($40), albeit with a bandwidth cap of twice the storage at any given level. As such, Mega is mostly a bundle of potential — but it may stand out from the pack if ambition matches reality.
