Hi,
Just installing something like Classic Shell, or a number of other free programs will work wonders in making Win 8\8.1 like Win 7... plus you still have all the new features if you decide you want to use them...
My favorite is Start 8, but is costs $4.99 with a 30 day free trial... I've not tried any of the newer versions of the free ones.
Way cheaper than a MAC, but that's up to you.
