One change that Apple made to the new iMacs beyond their revamped chassis is the addition of FireWire 800, which hasn’t seen much support beyond a few external hard drives. A good thread on MacSlash created before the new iMac introduction notes that FireWire remains important to Apple’s migration strategy via target disk mode but it seems that eSATA is gaining more momentum in the marketplace for external storage. On the other hand, Apple leveraged FireWire to bring the iPod into the marketplace so perhaps FireWire 800 will open doors to some new device down the line — an Apple camcorder perhaps?
