Profile Driven Storage
IMHO profile Driven Storage is not value for money, it is very crude and most enterprises will have expensive Sans that will do this tiering already and far more efficiently.
As for all that software driven datacenter malarkey, I think as you say it is appropriate for enterprise. But I don't see any benefit for SMB. 25 hosts being a good place to switch to DVS and host profiles. With a modern HP 2 CPU gen 8 server I would expect 40-50 vms per host so 1000 vms on 25 hosts seems reasonable and I class this well above SMB.
Good article, but I really find little value for anyone below 25 hosts in the enterprise suite now. Either switch to standard edition or jump to Hyper-V.
In 5 years VMware will be heading toward Novell and banyan vines territory if they keep purchasing third party products and then badly integrating them into their product suite.
As for SSO don't get me started. What is the point have they not heard of A.D. And linked mode.
