Google Drive is now available with up to 5 GB free space for cloud storage.
Only problem is that most everything in the editor is disabled. This will hopefully be fixed soon and also be able to open and save drawings to Google Drive from within AutoCAD WS.
Autodesk’s Pixlr Editor is also available as app to edit images with.
The search in Google Drive is cool. If you have images available to search among Google Goggles technology is used to recognize objects, logos, landmarks, text and much more.
On the topic of online storage. If you used Microsoft’s SkyDrive the storage is dropped to 7 GB but if you want you can reclaim your previous 25 GB if you log in now. Another cloud storage option is Dropbox (with a minimum of 2 GB free storage) that is quite popular but will probably get it tougher with the competition. One thing Dropbox has is version control of the files. Microsoft has a chart comparing the services.
