20 inch iMacs Bump 17 inch From the Education List

"Apple this week quietly announced plans to begin selling an aluminum 20-inch iMac configuration to qualified educational institutions for just $899, effectively closing the book on the white 17-inch legacy model that had previously assumed a similar role. Buyers authorized to make purchases for their educational institution can begin pre-ordering the new aluminum systems today for delivery in about a month. Each $899 20-inch iMac includes a 2.0GHz Intel Core 2 Duo, 1GB of memory, 160GB hard drive, 8x double-layer SuperDrive, and a NVIDIA GeForce 9400M graphics subsystem."

So that is that for the white iMacs. This is only available for educational institutions, however. Individuals who meet the educational discount requirement don't get the same deal, in case you were looking and couldn't find it listed.
