Recently I became I huge fan of Opera and with the new Version 9,5 it looks even better.
Already got rid of Firefox would love to get rid of IE7 but I cannot since my bank decided to use a stupid little application which only runs with IE and I need access to some software support sites which are not working with Opera.
I also downloaded Opera mini to my sonyericsson mobile phone and now surfing around 3-4 times faster (!) mobile than with the crappy built in browser.
Tip: download and try!
