Backpedal, full speed.
You said "have had less than half the "years" to upgrade as XP users have". It looks to me like the same claim, in slightly different tense and word order.
XP users did not have a chance to upgrade before 30 January 2007, so the first 6 years of your "~9 years" is moot. Nonsense. Ludicrous.
Let's check the statistics in February, OK?
My bike still moves forward when I back pedal. I don't go for the cheap $50 dollar bikes that come in a box.
