Clarion FB275BT car stereo - Look Ma no moving parts

Clarion has done some out of the box thinking for the FB275BT car stereo, it is very unique as it does not have any moving parts so no optical drives or onboard hard drive. There is not even onboard flash memory so how do you play music, it has a SD card slot for loading up your tunes. Very impractical I would say as you are bound by the storage capacity of the SD card and you have to delete old tracks to load new ones or buy a new card which is not viable as they are still very expensive when compared to a blank CD-R which costs 30 cents. Other than this the stereo has a FM tuner and Bluetooth connectivity for handsfree calling. It delivers an output of 50 W x 4-channels.
In case you are still interested the Clarion FB275BT will be available by April for $ 250.











I understand that some people like CD-Rs because they're cheap, but what the heck is practical about them?
