Galaxy Player 3.6???

OK, so scouring various tech sites such as engadget frequently, I was already aware that there was a recent Galaxy Player 4.2 released in other parts of the world, even though I fail to see the point when you already have a 4 inch and 5 inch model already out. But imagine my surprise when I walk into my local Best Buy and browse through the MP3 player section to find a THIRD Galaxy Player model on display. But it wasn't the 4.2 inch model that I had previously heard about, but out if nowhere I see this Galaxy Player 3.6! And I'm thinking to myself, why on earth would you make a 3.6 inch device when you already have a larger 4 inch device on the market? You didn't go bigger, instead you went SMALLER? Only 0.1 inches larger than the iPod Touch that you are trying to directly compete with? I mean its bad enough how iSheep always knock Samsung for "copying" Apple all the time, but this doesn't exactly help Samsung's case very much. I just don't understand the NEED for such a device...
