I hate to keep pushing Firefox (I will try and make this the last plug
, Honestly, I don't work for them) The have an add-in that displays the weather on the bottom right hand tool bar of your browser. Since it runs in the status pane next to the security icon it doesn't take up any extra real estate on your screen like some search tool bars do.
Just an FYI, most people only use IE since it is what is bundled with their computer, about 4 or 5 years ago I made it mandatory at my work that everyone must use Firefox and we have had a lot less computer problems.
It's kind of like a Mac(no offense meant) that if you were a computer hacker why waste time on a machine that is not used as much, the same goes for browsers. Windows and IE are by far the most popular so that is what hackers target.
