Let me get this right - Win 8 sucks for corporate use!
No, you got that wrong. Windows 8 is fine for corporate use, in fact, it behaves in the same way as Windows 7 for the most part.
It's like theres no appetite for it so software vendors aren't exactly rushing out newer compatible versions.
No idea what you are even talking about. Any Windows 7 software will run on 8. If you are looking for Modern UI apps to publish across your AD, then we write our own appx's and publish with SCCM.
Yes it does
SCCM pushes out Forefront Endpoint Protection no problems at all.
New VPN client from which provider? We run the same version of Cisco AnyConnect across 7 and 8, even if we didn't, the ASA5512's take care of that and upgrade the clients on connect (or via the web portal).
My thoughts exactly.
all of which I wouldn't mind but the fact SCCM 2012 requires upgrades (to latest sp, and then some!) our AD infrastructure would ideally need upgrading too!
You really should be running System Center 2012 SP1 anyway, 2012 was full of random holes and bugs. R2 is beautiful, but I'd understand why upgrading to R2 is a bit more of a faff.
No way this is gunna happen over night!
No, it's not. But any IT administrator worth his salt can schedule a project to upgrade System Center in a relatively quick timeframe. It's not as if SP1 hasn't been out for donkeys years anyway, and it's not as if Windows 8 snuck upon you overnight!
If it wasn't for the fact machines supplied with Windows 8 no longer have support for Win7 drivers
x64 drivers for Windows 7 will run on Windows 8 x64, and x86 drivers for Windows 7 will run on Windows 8 x86. No idea why you'd think any different?
Seems like a lot of negativity there against Windows 8, when in fact, the actual problem appears to be the mentality of the IT department.
