Microsoft made the Windows 8 Developer preview available for download some time last night. Today, around 12 hours later, Steve Ballmer has revealed at BUILD that more than 500,000 copies of the 3 GB operating system has been downloaded.
Noting that Microsoft expected to ship 350 million copies of Windows 7, and that at least 500 million Windows 7 PCs will be upgradable to Windows 8, he said:
“There is no phone, there is nothing on the tablet, there is no operating system on the planet that will ship 350 million units of anything other than Windows,” he said.
“To me this all adds up to an unprecedented time of opportunity for developers.”
Windows 8 presents a great opportunity for developers to sell updated Metro versions of apps which already exist for Windows 7 and below, creating (for developers) the fortunate environment of a massive installed base with few apps and a populace hungry for the same, suggesting there may be an even bigger gold rush for developers to Windows 8 than the iPhone App Store.
