This combination works really fine the 770:

yubnub ( http://www.yubnub.org ) - "command-line web interface" - to avoid having to type too many letters (for those of us who don't have a bluetooth keyboard, or who don't want one).

yubnub mobile - there are several variants of yubnub using less screen space

skweezer ( http://www.skweezer.net/ ) compresses and reformats Web content

all taken together: http://www.thebogles.com/yubnub.html

and it even accepts parameters directly:
this one "g Nokia 770" googles for Nokia 770: http://thebogles.com/tools/yubnub.py?q=g%20Nokia%20770
this one "wp Nokia 770" searches the 770 in Wikipedia
http://thebogles.com/tools/yubnub.py?q=wp%20Nokia%20770

what would be nice (Developers out there...): a small yubnub application for the 770's home page which just the command line input field. Replacing the link to the "Nokia" homepage.
