Note to all Mathematica 10 users: bug-fixes will not be available to anyone unless you:
a) have a Premium license
b) have Annual Home Edition, currently 150 dollars per year
c) pay 95 dollar upgrade fee for every dot-release
Version 10 has already had 2 dot-releases)
It is unclear whether you have to buy every dot-release (who knows how many there will be per year???).
Logically, it is to be expected that every dot-release has to be bought otherwise people would just buy every second or third dot-release and get the benefits of all prior dot-releases at a discount.
If only Wolfram had made this clear up front - I would have bought the annual subscription. Massive disappointment.
Caveat emptor!!! or, "Home Edition users beware!"
