Vista up to 19% worldwide share - by web hits

Windows Vista Market Statistics

OK here’s some rough calculations:

19.29% of internet users are Vista

1.46 billion internet users

Assuming the usage rate is consistent around the world…
1.46 billion * 19.29% = 282 million Vista internet users

The actually user base would be significantly less than the above number only if for some reason, Vista users surf the internet WAY MORE than all other OS's to skew the percentage up to 19.29%. It’s probably more likely that that some Vista users don’t use the internet much because it’s for work mostly. Hence there is likely more than 282 million Vista users.

Hitslink logs statistics in the “rich” (and more regulated) demographics. Here Vista adoption is probably held back a little by expense. So that could mean that Vista adoption in other “poorer” (Gov’t don’t give a crap) nations is much greater than 19.29% since you can like buy it at the local fruit shop for like $1, etc.

So, if you include ALL of Asia? 500 million Vista users???
