Over the last 4 months b2cloud has been busily building Google Glass Apps for the most forward thinking companies in Australia. Not to mention the neat little Apps we have developed for demonstration at events around Australia including Glass Tabs – Learning guitar through Google Glass.
If you're a developer and you find your HD space just seems to disappear without your putting any new files on your computer, take a look into what Xcode is doing. For every project you create Xcode will cache a lot of data for intellisense, autocompletion, and some other features. Whether it's a test project or a full on client project, Xcode will keep this data until you delete it. On my laptop I don't think I've deleted any of this data for about 8 months, which worked out to be roughly 16GB worth. This includes archived apps I send to clients for testing purposes, stuff that I consider to be a one off.
