I have been attending Teched every year since 2005. Last year, I really did not like the separation that was "forced" between IT Pro and Dev. I like to attend sessions from both areas - SQL covers both areas. I am glad they combined it this year (as it should be IMHO). Once again, I will be in the TLC area where I LOVE to be. The TLCs (Technical Learning Centers) allow you an opportunity to get questions answered by MSFT and User Experts. They also give away some pretty good SWAG too.
Another reason that I like TechEd is that it allows me to expand my education on areaa of SQL Server that I usally do not have normal contact with. This is another reason that I like the combined version.
If you are heading to TechEd, please spend some time in the TLCs and say "HI".
