They could always build in support for a USB mouse in such a browser. Also, you can already hook a 360 to a monitor, and with the rise of HDTV, it's less of an issue to do something text intensive like read web pages on such TV's compared with the mess it was on good ol SD CRT's.
Remember, the 360 is not a PC. The core of its brand message is that it is not a PC; it lives in the living-room, not in a geeky study, and it attaches to your TV not a geeky monitor*. Its peripherals are usable on your sofa, not a geeky desk. It's viewed from your sofa, not sat right infront of it like a geek. Its games and movies are social, not solitary.
To release a peripheral that requires a desk to power an application that is only interesting to one person up-close is a direct contradiction of its brand-message. Hell will freeze over before the 360 supports a mouse**.
* Note that you need a fucking gender-bender just to attach the 'VGA' lead to a VGA monitor!
** In released code. XDK had built-in mouse support with XMOUSE (X being the prefix for 'use this library and there's no way in hell we'll sign your code').
