For those who roll with unified browsing and emailing in a single bundle, Mozilla's SeaMonkey software, which has just been updated to version 2.0, might be just what you're looking for, provided you're a fan of Firefox and Thunderbird.
The newest version comes retooled with Firefox 3.5.4, and as a result, Mozilla says it's much closer to the the standalone browser, at least in terms of user profiles, add-ons, and functionality of UI elements. That also means it now incorporates crash recovery so you needn't lose your browser windows, tabs, and even data entered in web forms should something bad happen.
But it's not all about the browser. On the email side of things, new IMAP accounts now keep local offline copies by default, which ranks as one of the speed tweaks Mozilla implemented when working with IMAP. Tabbed mail has been added, and the mail module lets you subscribe to RSS and Atom feeds discovered by the browser on Web pages.
