wavedreamer, I agree with all of that.
The BIOS issue isn't a deal killer per se, I expect it to negatively impact the rate of deployment.
SKS indicated that the BIOS issue is a matter for machines more than a couple years old, the actual slice of the pie that the more difficult machine represents is unknown, but presumably less than half.
If somebody is going to solve this, it would be Wave. They have worked with and worked out compatibility with all sort of bioses, TPMs etc for some time. Nobody is more fluent (IMO). In a sense, this legacy cluster-stuff is an advantage for Wave ... its one thing to enter a shiny new market with a shiny new product, its another to enter a market with legacy problems and try to compete with a firm so fluent and entrenched in the nuances (indeed has made dealing with the nuances a part of its business plan).
Again, its an adoption rate issue to me, but a rather important issue in my estimation.
The above content is my opinion.
