Hyper-V is far more flexible than VPC/XP mode which can't even do x64 guests (we've had to use virtualbox for this which is a lot kludgier than hyper-v. Your users may not have the need.
"Possible win" - sounds like you haven't tried DA (or don't have many laptops, which was our case up until fairly recently - now it is almost a necessity). It rocks and 2012/8 make it deployable with 4 clicks.
Obviously you shouldn't deploy if you have compatibility issues.
I didn't say vhd, I said VHDX (we are now standardized on VHDX across all 8/2012 machines - previously we had a mix of VHD/VHDX which is inefficient and doubles storage).
As I said, our users (and the vast majority of end users) don't need virtualisation, and our VM platform is vSphere anyway, so end user hyper-v = meh. The only end user desktop virtualisation we'd really consider is either App-V, VMware thinapp, VMware VDI thin clients, or XP-mode, which we haven't needed yet, and have been running Win7 on all new installs since early 2010 - we're probably 95% win7 now and the only reason for the stragglers is non-funding, not compatibility with apps...
For DirectAccess, I say possible win because I haven't rolled it out yet. Have had mixed reports from guys here who have, admiittedly none of them were on 2012 server so again, point there, agreed. I have a few hundred laptops (asy, 90% of our users), so don't get me wrong I definitely see the need and want to see it work. But you can work around no directAccess - we do remote support via Lync if outside the firewall and SCCM can be set up to work over the internet without IPV6 tunneling too.
As far as VHDX goes, i know you said that and not VHD, but if you're not migrating to 8 / 2012, you don't have VHDX so there's no need for 7 to mount it...
Not sure why you're saying that Windows 7 can natively mount ISO files; it can't.
My bad, it's been ages since i worked with ISOs actually inside an OS you are correct.
Printing is a big one. Previously we had to have a minimum of two physical machines at each branch for redundancy purposes (which practically boils down to printing since other services can happen over the WAN). Win8/2012 fixes this in a couple ways - one is that the windoze client is finally smart enough to simply print to the printer directly if the server is offline.
Fair enough, we virtualize our file/print on a VMware HA cluster, and run updates out of hours so don't really have an issue with unavailability, but I guess that's a win.
Our WAN links are pretty crappy (remote locations with poor comms availability) so centralised printing controlled by HQ is no real gain for us.
I agree with you on metro apps - it's mainly consumer-focused and going to be a very gradual thing on the corporate side. I don't really agree that it hampers use of win8 in any way though. There are many days I see the start screen once a day.
It's not the start screen so much...
Metro just doesn't work well with a mouse and keyboard, period. And touch when i'm at a desk is no use to me, as my preferred viewing distance for my multi-monitor setup is beyond convenient arm's reach anyhow. Never mind gorilla-arm syndrome, I'm talking hunchback of notre dame.
I really think microsoft screwed up here, but I *can* see why they are attempting to force it on desktop users - because it's the only way they think they'll be able to get desktop apps written for it which will then give them a foothold in the tablet market.
But the end result is just a dysfunctional inconsistent desktop interface that breaks a lot of things to boot.
It strikes me as if Microsoft just don't have confidence in their mobile platform (and after many versions of WINCE failing, I can understand) and see the only way into the market as piggybacking off the desktop.
Which again, I think is a mistake - different form factors and screen size demand different interfaces - it's the whole reason iOS and Android are the way they are, and why they took off whereas the myriad of x86 tablet based machines running windows since the early 2000s were very, very niche and pretty much a failure.
But, they appear to have bet the farm on it and have quite a lot of money to throw after it for some time yet.
Its just a damn shame they aren't writing something BETTER that is more forward looking - the whole disjointed Windows 8 UI and much of the bloat is due to the refusal to give up backwards compatibility, as has been their way since DOS.
They have the people and the money to make something good, it seems their products just get stuck in the design-by-committee mud and compromised because of it - they're trying to be all things to all people, when what is really needed is a more focused device that is good at what it does rather than mediocre at everything.
