Being a Zen owner for a few months now, I could see but one major problem in what was offered to me as a Zen customer, over say an Apple customer. The accessories!
I couldn't pop onto the high street and stumble across a nice way to protect my Zen mp3 player or change it's appearance, yet if I had an iPod I could hit stalls full of different covers and cases, this is obviously because of their high popularity among the general populace.
But lo my prayers were answered! I went onto the internet and found that Zen were now offering skin packs! Although they weren't as varied as the hundreds of official/bootleg skins and cases for Apple products, it's better than nothing, right? It fits the model of Zen product seamlessly and easily, with access slots for earphones, charging and also the speakers on the back if you happened to have purchased that model. The silicone is strong and tearproof, and seems to have been manufactured well (no rough edges, or scuffed up appearance from the box).
Exactly what you expect, and a good price too!
