Do you visit technology expos?

I love to visit technology expos because they showcase the most recent advances in the technology field. I vividly remember when I visited a technology expo when watches with laser time displays were only coming to the market. I bought one also with quite a hefty price tags but they were quick to go away from the market :(

I usually find myself waiting for the middle east technology expo every two years which is conducted just 15 KMS away from where I live.
