Microsoft Not Yet Ready to Describe What "Supported Lifetime of the Device" Means for Windows 10

There's been much debate over Terry Myerson's echoing statement about the free upgrade for Windows 10 users at the company's grand event on January 21, 2015.

Terry said this…

This is more than a one-time upgrade: once a Windows device is upgraded to Windows 10, we will continue to keep it current for the supported lifetime of the device – at no additional charge.

The debate is over what exactly "supported lifetime of the device" really means. And, there's the rub: It would seem that Microsoft doesn't yet know, either.

In a blog post last week that talked about Microsoft's new servicing ideas for Windows 10 in business situations, and outlined how Windows 10 will not be a free upgrade for SA customers, Microsoft's Jim Alkove reiterated the free upgrade for consumers, but a set of guiding asterisks (**) led to the following clarification:

**Details on our device’ supported lifetime policy will be shared at a later time.

So, it would appear that the company is still working out the details, and we have nothing truly to debate – yet.

What's your take on the debate?
