Cross borwser compatiblity - some facts for web developer

I just came across some interesting facts for a web developer.

Internet Explorer(both IE 6 & IE 7) is being used by around 65% of the users, Where as firefox is being used by around 25% of the users, and the remaining percentage goes to browsers like Safari, opera....
So if you are a web developer you should be aware of these facts and the application you develop should atleast support IE and Firefox. You should test your application for these two major browsers which takes up 90% of the market.

And when we look at the Operating Systems usage, Windows dominates the market with around 95% of the users, remianing 5% is being shared by Mac and Linux. So it is not a harm if you neglect the testing for mac and linux.

When we look at the screen resolutions being used, 1024 x 768 takes up 50% of the users and the remaining percentage covers all other resolutions. So the application you develop should look good in all the screen resolutions.
