This is exactly the definition of a multimedia device. It’s the iLuv i1055, a portable DVD player that has an iPod dock on the back.
The intuitive use of this is plopping a Video iPod in that dock on the back, running a S-Video cable between the dock and the 7-inch screen, and watching your favorite videos or movies.
You can power this baby three different ways: by the more standard 12V cigarette lighter, a plain old 10-volt AC adapter, or the more new wave NiMH rechargeable batteries. A remote control case, headphones, and carrying case complete the offering.
Price is US$230.
