Last year we got this great USB key with ESXi loaded on it. It was one of the best handouts. It also came in handy back in the office as it was easy to simply drop off that USB key and allow any department to evaluate and use ESX on their servers. It was handy doing demos and seeing the different hardware virtualize.
This year I have not seen anything like it. I hope someone takes notice and does this next show. Getting the software into hands of people back in the datacenter or office after the show has proved invaluable.
Seems some few people did get a thinapp keyfob from Kingston.
