My favourite browser, Opera, is now updated to version 10. I like this application because it combines my browsing and mail requirements into one app - negating the need to run two separate applications. Mail resides in a tab, just like any other web page - and it's a fully-featured multi-account IMAP/POP client, not just webmail. A nice clean look too for the latest version. Very fast and on a smaller footprint than Firefox.
