I am just wondering before investing 1500~$ in a workstation to run the SP4 VIRL topology, has anyone been what they would call successfull using it?
 Two things that make me wonder is that the workbook still says "beta" and is a 95% copy/paste of the SPv3 book without any update to topology.
I was thinking of buying SP workbook, but I heard it is not ready yet, so I'm waiting till its complete.
Rental rack is not available yet, so there is no point of hurry.
New SP WB is out yet? any timeline?
