Query: Muvo reconsidered

I've now had some experience with my second Muvo and found that both units:* will not play some .wma files that MS Media Player and MusicMatch will play - the Muvos power themselves down at the same spots.* Both Muvos have shown signs of corrupting their flash memory - the common one being self labotomization: the flash area with files may look ok, but the Muvo will no longer power on. You must go through a special hard format procedure that restores the Muvo firmware and hard formats the flash memory.Finally there is a major misfeature in the Muvo. When powered off the Muvo always returns to the first song. With no random play function this means that you will listen to the first 30 min to 1 hour of music over and over again unless you do a lot of button pressing.I think the Muvo is a great idea, but the execution and quality should rule it out for now.
