Ya. When you have 50 computers and requiring a full OS upgrade I can see why business are not eager to make the leap. OS upgrades are not fun — I have done a few — upgrade the OS (at least an hour, maybe two), reinstall the apps, cross your fingers and hope that the drivers exist for your hardware, etc. etc.
But now they won’t have a choice.
Too bad MS won’t sell the source to a third party for continued support. We’d be willing to pay a fee for monthly support.
They have a choice: don’t upgrade. Really if their stuff is working they don’t need to upgrade. If they needed to upgrade they would have already.
