Google just clued us in on a couple of major changes to the Android Market. First and foremost is that the size limit on applications will soon be increased from the current 50MB to a massive 4GB. That's going to cut down on the secondary installs -- where you install an app only to be told you need to download more data -- and instead you'll just download that massive amount of data directly. Six of one, half-dozen of the other, we suppose.
And another cool tool for developers is the ability to easily keep your app from being installed on any Android phone. Devs can manually choose any device to blacklist, or it can be done through the manifest, too.
