I am thinking about purchasing the Sony NW-HD5 unit. I am very aware of the button cracking issue, but it does not really bother me as long as it's still fully functional. Anyway, does anyone know if there are any nice carrying case for the unit? In particular, silicon cases. Also, I couldn't decide between silver and black unit since I haven't seen them in person. For those who have actually seen this unit, it would be nice to share some opinions. Thanks.
