Ah, now you see its not THE browser of choice, in my opinion Opera beats it hands down.....

little things like

cross platform ( windows, linux, symbian, apple etc)
sync'd bookmarks and history across all computers I use
voice feature to read out techie books/pages whilst I'm doing other stuff
thumbnail tabs that I have on permanently
decent built in RSS client
easy to set and site level preferences
auto reload feature

the above are a few odf the built in bits that make my internet life so easy, some can be done by using add ins to firefox but with Opera it all just 'works'
