After a little more than a week of using Phoenix as my web browser of choice, I'm definitely liking it. Smaller than Mozilla, but still renders everything properly. No silly e-mail, news or chat clients included. Just a browser.
My favorite feature, so far, is this. Not just tabbed-browsing. But the ability to create a folder full of bookmarks, and then open them all up at once. Reading my daily blogs has never been easier.
As a side note, I will at some point make some changes to the site so it looks better in IE on Windows. Of course, since there are plenty of alternatives to IE (1, 2, 3, 4, 5, 6), don't expect me to rush on this :-p
