I was tring to find one to buy well before xmas and was unable to find any =(
PocketBook doesnt have any retailers in the USA any more as far as I could tell and the prices at the time to get one over seas wasnt worth it.
Its really a shame, I still have my going on 3 year old pb360 and love it, would have loved to get another one.
As a side note, if you cannt find a pb360 check out the BN Nook simple touch glow.
Its a nice alternative, not quite as full featured as the PB360, but has nice features and supports directory structure to customize how you store your ebooks on it.
