Is PC a safer purchase than consoles due to the volatility of the console market?

And the OP's claims of volatility seem... weak. Sony's "Disaster" PS3 gen still won the gen over-all.

PS3 didn't won. History rewriting?

I'm simply basing off sales trackers which show PS3 beating 360 by about 1m despite 1 year delay, both on this site and others.
The point at which Sony passed MS appearing to happen in late '12, based on Sony/MS own reporting of sales:
http://www.itworld.com/article/2714950/personal-technology/idc--total-ps3-sales-top-xbox-360.html
"Microsoft has said that as of September 2012 it sold 70 million units of its gaming device, while Sony has announced it sold 70.2 million."

Is it unreasonable or surprising to base discussion off of such reporting? Is it not "rewriting history" to dispute those long established figures? If you have some other source you can establish is more credible, I'm all ears.  5 word zingers hardly contribute though.
