I'm coining a new term: Upgradegradation. A combination of 'Upgrade' and 'Degradation'. When you install an upgrade to a product only to find that certain features have been degraded requiring additional licenses or monies in order to re-enable the original features.
Example: I performed an upgradegradation from Windows Server 2003 Standard Edition to Windows Server 2008 Standard Edition and found out (painfully) that 2003 supported unlimited DFS roots, but 2008 only supports one. To regain the unlimited DFS roots, you must purchase Windows Server 2008 Enterprise Edition which costs significantly more.
F*ck you Microsoft.
(The term is based off one a Dell technician used on me--I was told I should 'upgradate' my processor.)
