Too much money
Here's the bottom line. Windows 8 is going to cost your firm a lot of money, both in direct costs and in training time to familiarize employees with a desktop that will only get in the way of their long-honed Windows skills. For that investment, you get no appreciable benefits.
Want something that will work well for you and your company? Stick with Windows XP. It's supported until April 2014. Or move up to Windows 7. You can still buy it on new PCs, and it's supported until at least January 2020. Want to try something different, better and cheaper that won't require as much retraining as Windows 8? Then take a look at Google's Chrome OS.
Whatever you do, stay away from Windows 8. Your IT staff will thank you, your employees will thank you, and, perhaps most important of all, your CFO will thank you.
