As for the issue of upgrading large orgnaizations/governments/schools to something beyond XP, if it hasn't been done already and/or it can't be done by 2014, one of three things is the issue.
1. Incompetent or apathetic IT staff.
2. Stubborn or equally incompetent software vendors (whaddaya mean 16 bit apps don't work in 64 bit windows!?)
3. Short-sighted and ultimately incompetent management that wont give the IT people the resources needed to do the upgrade.
4. Government spending cuts - do more with less, including IT staff and $ for software. Although that could be considered covered by #3, if you consider politicians as "management." Mismanagement, maybe...
5. Old legacy software that needs to be updated/replaced with something else... ties into #4 above.
We're targeting next year as the date to move to Windows 7, and I don't look forward to it... We've been rolling out Office 2010 to 25,000 or more PCs, and it hasn't been issue-free. End user training? Available as online tutorials only, and everyone is too busy to bother with that. Hence the Help Desk (my workplace) gets plenty of calls that we never should have gotten in the first place.
