First, show me where I said anything about a typical corporate environment.
That would be the part where you're making a sweeping, generalised judgement call. It seems reasonable to assume one of the most common scenarios would be encompassed.
Yeah. I'm funny like that. I think an order of magnitude increase in bandwidth has the capability to be more useful, and conversely an order of magnitude less could be considered "less useful." If 100Mb wasn't "less useful" there wouldn't be a 1 Gigabit standard.
However, this difference does not happen in isolation. You are trading off bandwidth against POE.
Ultimately, the question becomes: is 1Gb more useful or is POE more useful ? My answer is that in most common corporate environments, POE will be considered more useful because 1Gb is largely unnecessary.
I'll try to put it in a way you can understand. With Gigabit it has potential to do real computing ... e.g. boot Linux with PXE and access a data store in a NAS, for example.
100Mb is quite adequate for this.
I don't care what it was designed for, nor did I claim that their design decisions were unsound. The whole point, which you are working so hard to not get (perhaps because you are too busy putting words in my mouth) is that anyone who had an idea of using this in some very cool applications with visions of high performance networking at their disposal and powering it with PoE is SOL.
Your original comment in this thread was: "... which drops to 10/100 when using PoE, thereby making it only marginally useful for very thin applications."
Which is patently false. 100Mb is not only very useful for just about anything anyone would want to do with a thin client, it's also quite adequate even for normal, managed desktop PCs booting from local disk and accessing data off the network. It's even adequate for thick clients booting over the network, as evidenced by all the places that not only did it before they could get gigabit, but continued to do it for years afterwards.
Fundamentally, the marginal utility of 1Gb over 100Mb for most end-user computing scenarios is very small. I know of several companies that have, within the last five years, replaced their entire office networks (multiple floors in multiple buildings, thousands of endpoints) and chosen to stay at 100Mb for ~95% of endpoints because no benefit (to justify the additional cost) was perceived in going to 1Gb.
Obviously HP put Gigabit capability in there for a reason (you did know that companies count every penny and add up the cost of the BOM, right?)
1Gb adds SFA to the cost of the end user device. It adds _shitloads_ to the cost of the networking infrastructure to support thousands of those devices.
