Dropbox has recently released an optimized app for Windows 8 users. This app is a tablet friendly one and available at the Windows Store. The Dropbox app will run on any Windows 8 platform which includes the hybrid laptops with touch-screens along tablets like Surface RT which do not support all applications that run on Windows 8.
Unfortunately Dropbox has still not released an app for Windows 8 phone platform.
Is Dropbox App in Windows 8 worth your time?
A Dropbox app is still not available for Windows phone, but with this update that update should be available sooner rather than later.
Try out the Dropbox app if you have a Windows tablet and let us know your views in your comments.
