well the muvo is 2.5 times the size, almost double the weight, and the battery life according reviews i saw on amazon can be around 3 hours with an AAA. also, with the smaller storage capacity, it wouldnt have been much use to me since i am using mine as a flash drive. the reviews on amazon seem to state the player dies and is cheaply made. maybe since apple is selling these shuffles like crazy, the other companies will do it too. i didnt want to wait for them to copy, though.
also, i think you might be waiting a long time for a player the size of the shuffle with bluetooth. from what i have heard that would kill batteries, and battery capacity is limited by 2 things size and science. neither of which seem to be changing very quickly.
