MD_Titus:
There's no DX11 mode yet for CoD. Also, we don't get 3 activations per month. We start with 3 and get an additional activation every month to make up for the ones we already used, but the total can't be higher than 3.
So, when i install on my PC i'm left with 2 activations, after a month i'll have 3 again, but one month further down the line i will still have 3 since it's the upper limit.
I hope this makes sense.
As for installing on both the mac and the macbook, it would be no problem. It will just mean using two activations during the first month instead of one, but other than that it will be ok.
Oldschool: True, macs are overpriced and in the current day also very restrictive to the end user in some aspects and that's why i'm not touching them with a 10 foot pole.
They are also mostly used for non-gaming purposes and for some people specialized functionality to enhance productivity in a few select areas is worth the cost, especially if it's got something to do with their line of work and that's what the mac was all about since the 80s.
If you are judging every mac user according to the recent wave of "apple crazy" gadget collectors who just have to have one as a fashion statement (it does come off that way in your post, so disregard this if you meant something else) you're just widely discriminating against the preferences of some people that nobody forces you to share and a "get off your high horse" would be in order.
The way you worded it is similar to saying every flight simmer is a geek wannabe pilot who doesn't have what it takes to be real one and/or sucks donkey balls for not having the money or ability to become one. That is, it's not a very pleasant way to paint everything and everybody with a brush that's a football court wide when you are on the receiving end of such a remark and people judge you without knowing anything meaningful about you
