Alpine's cutting straight to the chase with its new iDA-X200 and iDA-X300 headunits. Forgoing a CD mechanism entirely, the two systems are designed primarily for use with an iPod, though they do pack a few extra goodies. The X200 works with Alpine's Sound Imprint system for some fancy DSP, while the X300 has USB input for pulling media off of non-iPod sources. No word on price or availability.
