On the
www.the-ebook.org forum I asked pocketbook representatives why the price was suddenly raised. Their answer was "due to various reasons but mainly because our russian and european customers complained about too low prices in US compared to Europe."
I highly doubt they would lower the prices in Europe if american customers complained about too high prices in Europe.
I was really interested in 902, but now I am not going to get involved with this kind of company.
P.S. From that same forum it turns out none of the new pocketbook devices is really working the way they are supposed too. They knew it, but decided to put them on the market before the holiday shopping season. Plenty of people, who installed their new firmware have bricked readers and now are waiting for a new firmware to bring it back to life.
