Fanime! started today, and I am currently en route to San Jose for that very reason.
As previously reported, Jon went in 2009, convinced me to join him 2010 (to which we did a five part followup), abandoned me for 2011, and all of team snowulf went last year (as covered by Jon and John).
This year, I will be there for the whole convention. Jon may or may not put in an appearance. The show is fairly inexpensive and a single day pass is between $30 and $40 depending on the day.
If you are still waffling about attending, take a peak at the schedule.
