Designing a Web Ad : Platform / OS Percentage Use

You might think that optimizing your site to run in IE, FireFox and Safari is all you need to do. However, you might be surprised to hear that the same website seen on a PC running windows XP looks different than the website running Mac OS X - even if both machines are using Internet Explorer as their browser!

It is well worth it to make sure you set up machines - or find friends or family members with machines - that cover the main flavors of operating systems out there. That way you can ensure your site works smoothly for visitors of all backgrounds and on all types of systems.
