Windows 8 is a disaster for corporate IT. Good grief, just switching from Office 2003 to 2007/2010 almost sent our users into apoplexy. Removing the desktop will send them into catatonia. I've got users that can't handle it if I change the name of folder on a network share drive or the name of the network printer. I am furious at Microsoft for doing this to the IT industry. They gave us NO transition path to allow us to deploy new Win 8 workstations without Metro. They don't seem to care that corporate IT still needs to install and maintain crappy old applications like Oracle eBusiness Suite (Java based and no significant upgrades in 3+ years), client-server based apps that are one step-up from green screens, and custom apps built 8 years ago using Java or Visual C++. IT budgets are tighter than ever and we have ZERO resources to keep up with the feature wars between Microsoft, Google, Oracle, Salesforce.com, SAP, Citrix, vmWare, and every 2nd & 3rd tier SW vendor - it is simply insane.
Our IT guys were thankful that we've stuck with win7 when 8 came out. They offer similar experiences when they swapped all of us over from Office 2003 to 2007, no matter how much tutorial information provided at the same time.
After years of using Windows, I've decided to treat the initial release as a giant beta test for any new OS from Microsoft, and will only install an OS on my home computers after Microsoft releases their SP1 for it.
