During day 2 I've been at Solution Exchange, where exhibitors show off state of the art technologies.
I've followed VCE, EMC and Cisco live presentations for now and is always a big pleasure: if you have spare time between sessions, definitely go there.
Great booth also by Veeam: you cannot miss it ( it is where people are all wearing green shirts :) )
At the end of the main corridor there is a free lab from EMC: go there too: vSpecialists from EMC will guide you into interactive demo ( let's say ... EMC Hands On Labs ).
Absolutely to visit: Dell, Intel, RedHat and for customers and partners involved in VDI project booths of Liquidware Labs ( that just announced "Stratusphere UX and VMware Branch Office Desktops" and F5.
