SanDisk displayed during this CES a new concept for selling music: pre-loaded inside memory cards. Thus you can insert this kind of card directly on your cell phone with MP3 capability or MP3 player to listen to the songs. What is really cool about this concept – called slotMusic – is that the package of the memory cards is on the same size of CDs and carrying the original CD artwork. Memory cards with pre-loaded music are already being sold at BestBuy and Wal-Mart. The price is very similar to a CD, with the advantage of bringing home a 1 GB memory card.
