Microsoft Points
The Microsoft Points system was criticized for being deceptive in terms of actual real-world cost, as well as for users often having to purchase more points at once than those they immediately needed. In his review of the Zune, Paul Thurrott argued that "a song on Zune typically costs 79 Microsoft Points, which, yes, is about 99 cents. But it seems to be less because it's just 79 Points." Walter Mossberg also noted that "to buy even a single 99 cent song from the Zune store, you have to purchase blocks of "points" from Microsoft, in increments of at least $5. You can't just click and have the 99 cents deducted from a credit card, as you can with iTunes. So, even if you are buying only one song, you have to allow Microsoft to hold on to at least $4.01 of your money until you buy another."
