The redesigned iMac desktop range emerges

Apple wants to be ready for the back-to-school and holiday spending spree and in preparation has unveiled a new, thinner iMac line.

I'll have more specifics later, but what I do know is that the new iMacs will have a thinner aluminum casing and sport 20 to 24 inch displays (the 17 inch line has been discontinued).  Prices of the new systems will be between $1,199 and $1,799 depending on configuration.

If you're in the market for the 24-inch iMac then I have some good news for you - the price has dropped by a cool $200.
