The thing that kills me is that XP is basically 10 years old now. It still "adds a new device" every time i plug in a usb key.
Microsoft has invested billions in Vista and Windows 7.
It's time to upgrade
Non-sequiter.You can buy support for legacy versions of VMS, Unix and OS/2.
Supporting all the legacy costs Microsoft money that
can be better spent on future enhancements.
It would be definitely be cost-effective to sell Windows XP support.The reason for withdrawing XP support are strategic, not cost-oriented (nor customer-oriented!!)
