The points system is stupid, especially those 160 or 240 etc. things that screw up the ratio so you always need more. However, on Windows Phone, you can pay cash with the correct amount and not use MSP. I've never used MSP to buy games on WP7.
I sent this to my father, the scout leader. Can't wait to see what he says. Maybe he'll buy me a PS3 so we can install it together, and I'll teach him how!
Poll: Microsoft might be killing MS Points in favour of real, actual, money. Praise be for (much belated) common sense?
