I arranged my Cebit (Sydney - May 2007) ticket the other day...  Over the past few years I have made a habit of dropping in on the CeBit exhibition as its a good place to get ideas and a bit of inspiration.  Just wandering around looking at products and talking to exhibitors is quite interesting... I usually manage to fill a few hours.  This year, CeBit features an expanded Open Source mini exhibition which in its 2nd year is proving popular.  I didn't actually end up getting down to CeBit last year so didn't get to see the response first hand to the Open Source side of things so I'm keen to see what happens this year.  Early bird registrations are available until March 15th so I would recommend a visit to www.CeBit.com.au real soon.
