I didn't want to derail the HDTV Advice thread, so I am starting a new one

One of my friends at work is looking at buying his first HDTV, so I've been passing on the information provided in that thread. He does have one question that hasn't come up yet... Is there a TV that will display the screen from his laptop wirelessly? I found the SW-4261 but haven't heard anything about it. Is that good enough quality for doing light graphical (not hardcore, but like pictures for PowerPoint) work or web browsing? Would lag be a problem in something like that?

I'm as lost as usual Thanks for any help.

Almost Edit: Ugh, after finding a couple user reviews, that product doesn't sound promising. Does anybody know of anything similar?
