Consumer Electronics Show Las Vegas: Free Registration
Anyone who can be anywhere near Las Vegas January 10-13, you can still register for the CES for free here http://cesweb.org/ ... price goes up to $100 after Aug 29 so if you have any interest in it, sign up and save yourself the money :)
It's not a DJ-show by any means but there are lots of gadgets of interest to djtt folks. Best of all, the Venetian hotel holds three floors or so of high end audio suites -- if you have any audiophile leanings whatsoever (or just want to hear what all the fuss is about), you can listen to the kinds of systems that only unlimited budgets can purchase, talk to some of the engineers who design them, etc. Well worth the trip!
