This is the iMac (Flat Panel) forum for G4 iMacs but I'm assuming that you will be purchasing a brand new Intel iMac so will provide details for those instead.
The following list is taken from this page (link)
- Mac OS X v10.4 Tiger (includes Spotlight, Dashboard, Mail, iChat AV, Safari, Address Book, QuickTime, iCal, DVD Player, Xcode Developer Tools)
- iLife ’06 (includes iTunes, iPhoto, iMovie HD, iDVD, iWeb, GarageBand),
- Microsoft Office 2004 for Mac Test Drive*,
- iWork (30-day trial)*,
- Big Bang Board Games,
- Comic Life,
- Omni Outliner,
- Apple Hardware Test
- Front Row
- Photo Booth
* despite Apple's TV Adverts both Microsoft Office and iWorks are both limited time trials. AppleWorks is still available for sale separately but is not optimized for Intel processors so has a limited life span. Therefore a proper word processor is no longer bundled with the iMac at all. Only the very basic TextEdit will allow you to type letters etc. You'll have to pay extra if you want more; so you could buy Word or Pages. Personally I'd recommend NeoOffice (link) which is a free download and unlike Microsoft Office is Intel native and compatible with Office2007.
Hope that helps.
