tdgeek: Acquisition question, that I don't think has been asked, but others may be in same situ.
While I have a Win 7 gaming rig, I switched to OSX a year ago, rMBP. I know I can dual boot to Win 10 preview now (or when its supported for Yosemite) with Bootcamp.
If I chose to keep Win 10, I would need to buy it (as not an upgrade) or can I upgrade Win 10 preview to the final release? I expect not, but just checking.
Is it possible that a free upgrade from OSX is available? Makes sense. If a No, No, will the consumer pricing be better than current full version traditional pricing, aka quite costly.
AFAIK speculation is that if you are running the preview then W10 will be free for you as long as you move to RTM in the first year.
