Vista's had quite a lot of negative press since it shipped, some justified, some not.  Some people who use it, love it, whilst others would much rather go back to XP.  The majority who would rather go back to XP, want to do so due to an initial bad experience, but if you're the bean counter in the organisation, trying to save money wherever possible, Vista's actually pretty good at saving you money, especially when it comes to power savings...

  • Windows Vista can reduce electricity costs. Businesses can save up to $11 per system, per year by switching to Windows Vista, due to the default power management settings. For a company with 5000 users, this means up to $47,000 of bottom line dollars can be saved annually.
  • The Vista Sleep state is more reliable than XP. Computers resume from Sleep in two seconds, which is about the same time it takes a screen to resume from Idle mode in Windows XP.
  • Power consumption reduction translates into direct CO2 savings. Carbon dioxide emissions are reduced by up to 67 kg of carbon dioxide per desktop PC, per year. For a company with 5000 users, this is 288 tonnes of carbon dioxide emissions reduced.
  • Aero graphics have no effect on overall power consumption. Organizations should take advantage of Aero since it does not have a significant impact on electricity usage.

Yes, Vista needs good hardware, but that's available now.  There's actually more supported devices and peripherals in the marketplace for Vista, than there are for XP now, and Vista is becoming more and more streamlined month on month.  It can also save organisation's a great deal of time and money when it comes to deployment, management and control.  The stats from above are taken from an Info-Tech report, which you can download and read here:

Obviously, for an organisation, the savings you make with Vista, only come about when you actually purchase Vista, and have decent hardware to run it on, but I guess with any investment, it's the savings over a period of time that are important, and that's what Vista delivers.  Yes, it's a change in behavior when using Vista for the first time, and for some people, there are still issues with certain applications (although the majority of mainstream apps are now certified on Vista) but give a user a good piece of hardware, and show them the ropes with Vista, and their productivity will rise, whilst you, as an IT Admin, have a more granular level of control over that machine, thanks to improvements in Group Policy, and the bean counter is happy, because you're going green, and saving cash.  This isn't going to happen overnight, but with SP1, more people are warming to Vista, and are becoming more willing to adopt, particularly when positioned well with Windows Server 2008.  Like I said, give people the decent hardware, control the machines well, and Vista in your environment shouldn't be the headache that many found it to be one upon a time.
