I went, first time.
Was it worth it - yes definitely.
I only did Friday pm and Saturday. I really enjoyed some of the talks - Andy Willis in particular. I didn't go to any of the seminars or short courses, neither did I buy much equipment.
However, next year now that I have a feel for the event I'll plan in more detail and attend some of the more specialist courses.
One thing they need to address is the numbers on the Saturday meant that some of the lectures were full - and I mean quite a lot of people not seeing what they wanted. The venues are just not big enough.
Also, having to queue 25 mins to buy a sandwich is not good.
