This was a pleasant surprise for me for sure. In addition to allowing users to remotely deploy applications directly from the website, Google has now included functionality to do a device compatibility check against registered devices.
I have an Asus Transformer Tablet in addition to my Samsung Galaxy phone registered and going into any application, you can now see which device the application will work on.
The market shows all applications regardless of device compatibility, so usually the only time you used to know if an application will work would be when you try and install it. Now, this message would save the users some time as well as looking very cool indeed!
