Not really anything to shout about, LOTS of 3D TV and related. Bluetooth seems to be getting all the attention with the manufacturers right now, even had a couple models capable of syncing with iPhone and Blackberry. One item that was interesting was a glove by Peregrine that is capable of being programmed into replacing keystrokes on your keyboard, mostly aimed at the gamer crowd.
Other than that it seems lots of people missing this year. Did not find Lenovo or Creative, and the booths seemed considerably smaller for those big presenters like Microsoft and Intel. A big push this year for interactivity.
As far as keyboards go there is more attention being paid to Mechanical switches, but membrane is still dominant in availability and design. Tried a couple new switches that were membrane but had very distinct feedback, should be interesting to see how everyone likes those.
Overall, it seems everyone is catering to CHEAP in just about everything, and very few seemed concerned with quality or lack thereof. Also, tried to find Ripster a new "model", but that offering was also extremely limited and lacked the quality this forum has come to expect! Maybe next year.
Later......MsKeyboard
PS....I think it is time we resurrect Comdex!
