Well so that's what Apple had up its sleeve.
A new iMac made of aluminium and glass with a new keyboard that matches the new design.
iWork 08 and iLife 08 with substantial improvements and slight .Mac enhancements to go with the updated iLife and iWork suites. For more details and updates please visit here.
If you can't wait till the Apple store is up, here is a little trick to get to the iMac site: type www.apple.com/iMac in your browser and you shall get there. Good luck and enjoy.
Update: The mac minis got the long awaited upgrades: new processors (faster), more memory and a larger HD.
