I am a big fan of the FireFox browser. The foxmarks extension which syncs your bookmarks across different computers is very handy.

The best thing though is the keywords for bookmarks. If you have a bookmark you go to a lot you can enter a keyword for that bookmark. Instead of typing in a URL you can enter the keyword.

Forget using the mouse to click on the address bar and then type in some long address, simply do a CTRL-L (or CTRL-T if you want a new tab) and then enter your keyword and hit enter. The keyboard is so much faster.

For people like me who are always looking up reference information on the same pages its a great feature.
