You'd think so (I know I did!), but I was floored the first time I started up Xombrero and saw that with only one tab, it used less than a sixth of the memory that Chromium uses. Xombrero has quickly become my favorite browser, though I only used it in the first place because I couldn't get any other browser that both 1) was not sludge on the Raspberry Pi, and 2) supports the modern Web (HTML5, CSS3, JS, ...).

It's not perfect by any means, but it is now my favorite :)
