If you've tried both of those I suggest you download the latest Opera (9.02). Oh it is soooo sweet.
You have to try using the mouse buttons to move back and forth in pages. Works really well in the Forums too. If you hold down the left mouse button and click the right mouse button it moves forward one page on a web page (so lets say you're reading a thread here with 7 pages if you're on page 2 for example it will go to page 3) To move back a page you hold the right mouse button down and click with the left. Very cool and I keep trying to use this feature in Windows when browsing folders. It seems like an insignificant feature, but it's amazing how much easier it is to surf the web, very addicting.
Also, has built in email, IRC, BitTorrent client, Widgets and more.
