speed of a "tablet" display...

...and even then you'd probably need two processors, one in the "main" computer and another in the display (the latter to process the compressed/encoded video sent from the main processor).
In any case, you would not have the same graphics experience with a wireless display as you currently have with a dedicated AGP port and a fast, local graphics processor.

One thing, in order to transmit uncompressed video at 1024x768 you would need bandwith that could support transfer speeds of roughly 3 MB/sec, or 24.5 Mbps. That is a lot of bandwith, and I don't think that 802.11g can really handle it despite the fact that it can theoretically handle 54 Mbps.

since i'm not a hardware superpro i'm not sure but 802.11g couldn't sustain 24.5 Mbps when it's hypothetical speed is more than double that?! that sucks!
fpnc:
here are a few options (i'm not sure if the second is possible since i don't have anything to compare to):
1. scale back the resolution.
if you scale back the resolution i imagine that you wouldn't need quite the bandwidth and thus you MAY be able to run it over 802.11g.
2. put a dedicated graphics chip in the screen as you suggested. i am not an industrial engineer but considering they can cram a G4, motherboard, harddrive, superdrive, graphics chip, bluetooth module, and all the according ports and fans, keyboard and screen into a 1" thick, 5 lb. device; i am inclined to think that if you can build an lcd screen that could run off a standalone graphics card with an 802.11g card, antenna and one usb port in it, thinner than 1", and lighter than 5 lbs.
how about this, throw a G3 in there to handle some processing as well? cheap, fast "enough" for processing video, etc...
i see the point that "this would only fit a small market" but it is my opinion that this would CREATE a market. one of those things that would make people say, "that is something that i really need!"
who knows, maybe until the next version of 802.11 can support uncompressed video at high resolution, X11 becomes a common thing, and TiVo functions could be built in and other features to add even more value it won't see the light of day.
oh well, here is one person that would buy one!
