For those of you who care about such things, I have info about the silver version. I was just about to snatch one of these up when I noticed this pic on Ebay :
So I fired off an email to the Hidizs company and they informed me the silver version will be available from August.
Probably of interest to everyone is that they responded within about 30 minutes.
and if you drop it, scratch marks on aluminum finish are not visible
