I arrived yesterday, in body at least. My laptop says it's 02:41.
However my mind knows it's nearly 7pm and I've already been through the "Sneak Peek" at PMA.

I didn't run around fast enough, spent too much time talking to people, only managing about half of the preview. But it gives me a sense of scale for this show.
Two weeks ago I was at Focus on Imaging in Birmingham which according to their PR is the largest annual show in Europe, that's about one quarter the size of the PMA trade show.

One thing caught my eye: lynda.com who provide online web based training, with closed captioning on the training videos. Not just that, but it's searchable on the captions, so for example you can look through all of the hits for "brush" in the Photoshop training course and then click on the links straight to the relevant video segment.
