Microsoft is always happy to take gently-used gadgets off your hands for store credit — hoping you'll buy a Microsoft product with the resulting cash — but as of late the company appears to be targeting Apple aggressively. Two weeks ago it launched a promotion where you can get a guaranteed $200 if you trade in any Apple iPad, and today Forbes is reporting that the company will extend that offer to used iPhones as well. The publication reports that starting this Friday, the company will offer $200 in store credit for iPhone 4S and iPhone 5 handsets at select stores in the US and Canada.

While that's probably a bit less money than you could get selling your device on the likes of eBay or Craigslist, and even other trade-in programs we've seen, it could be worthwhile if you're already dead set on switching to Windows Phone and want to do so in a hurry. Still, if the program operates as Forbes describes, the winner is clearly Microsoft. The company's hoping to steer those who planned to upgrade to the new iPhone 5C and iPhone 5S to Windows Phones instead, and it sounds like this promotion would do so without offering any more money than anyone else.
