Can the Aluminum iMac models run Mac OS 9/Classic applications?
No. Apple provides no support for running Mac OS 9 or the "Classic Environment" on Intel-based Macs like the Aluminum iMac models. Intel-based Macs rely on the "Rosetta Universal Binary Translator" to run software for Mac OS X for PowerPC, and this emulator cannot run "Classic/MacOS 9" applications.
Additionally, Mac OS X 10.5 "Leopard," Mac OS X 10.6 "Snow Leopard," and Mac OS X 10.7 "Lion," also provide no support for "Mac OS 9/Classic" applications. Mac OS X 10.7 "Lion" doesn't even support Mac OS X applications written for the PowerPC processor.
If you have a mission critical application that only runs on Mac OS 9, you likely would be best served by maintaining a PowerPC-based Mac. However, you may also be interested in reading "Are there any third-party programs to run Mac OS 9/Classic applications on Intel Macs?" from the Mac OS 9/Classic Support Q&A.
Can the Aluminum iMac models run Windows?
Yes. For those unfortunate ones condemned to use Windows, the Windows on Mac Q&A provides answers for just about everything you need to know about running Windows on the Aluminum iMac models or any other Intel-based Mac.
Can the Aluminum iMac models run Linux?
Yes. All Intel-based iMac models are capable of running a number of Intel-based distributions of Linux through Apple Boot Camp or by using "virtualization".
For more on Boot Camp and Virtualization, please refer to the Windows on Mac Q&A.
