Having read a few articles on Windows 10 lOT it seems to be saying that windows 10 is a free up-grade if taken within the year of release, they are saying one of its biggest down falls will be the having to pay for the up=dates ? Buying a Retail Version will include the up=dates Enterprise will pay a monthly fee Free version ??? I've asked Microsoft and they haven't replied ! If you remain in the insider they are free, drop out and you pay for further updates. ....and once you drop out, you can't get back in, with the same email... Anyone else heard this, there intension is to be like Adobe ?
