The minimum of $200 appears to be targeted specifically for iPhone users looking to trade-in and is part of Microsoft’s #timetoswitch program where they hope that the cash given to customers will be used towards a purchase of a Windows Phone product, or perhaps something else in Microsoft’s retail store. Perhaps this could help Microsoft gain some market share with iPhone users who are looking to make the switch, but at the same time it should be noted that Apple has a trade-in program of their own where iOS users can trade-in their older devices and get credit that can be used towards the purchase of a newer iOS product, so we guess it’s a matter of whether the Windows Phone operating system and hardware is enticing enough to convince customers to make the switch.
