I registered today for the upcoming TEK·X PHP conference in Chicago. I attended both ZendCon '08 and '09 but this will be my first TEK·X experience. I have heard that TEK·X is more of a community conference while ZendCon has a reputation for being more corporate. The schedule has not been announced yet (which is why I was able to get my ticket for 35% off). However, several people who have seen the schedule have said that there are some excellent sessions lined up. This year they are replacing the Unconference with a Hack Track which sounds like a lot of fun (even though I am a big fan of unconferences). Hope to see you there!
