Hi Tech 2008 has been great for me so far.
Some of the semiars have been very interesting and very detailed.
Howevever, i've notice a few hiccups with the demos (Things not working as expected).
I'm not sure if its do with the HK culture, but most of the audience seem very quiet - there is very little interaction with the Guest speakers. What I would like to see is alot of interaction between speakers and the audience to get everyone interested and involved.
Anyways I am looking forward to TechEd2009
