History: Announced in October 1999, The iMac (Slot Loading) was the low end of a new "good, better, best" iMac product strategy from Apple. The iMac SL built on the success of the rev. D iMacs, adding a faster processor, more RAM (64 MB base), a better graphics sub-system, an improved speaker system, and a slot-loading CD-ROM drive. With all these new features, the iMac SL was still $200 cheaper than predecessor. At $999 U.S., the blueberry-only iMac SL was the cheapest Apple-branded machine in many years.
