Les Numériques caught up with Pocketbook last week at the Salon du Livre, and they got a chance to dunk the new Pocketbook Aqua to confirm that it was waterproof. This is a fairly basic ereader with a low resolution 6" E-ink screen, 4GB Flash storage, Wifi, and a touchscreen, but no frontlight or microSD card slot.
It has specs about on the same level as the Pocketbook Basic Touch, a 69 euro ebook reader, but due to the additional cost of waterproofing the Pocketbook Aqua is going to cost 109 euros in Germany when it ships in the next few weeks. The Aqua is certified for the IP57 standard for dust and water resistance, meaning that it can be submerged in up to a meter of water for up to 30 minutes.
At 109 euros, this is a pretty expensive ereader considering the basic specs. On the other hand, the Aqua does cost abut $70 cheaper than an aftermarket Kindle Paperwhite from Waterfi, which costs $219. Waterfi offers an aftermarket service which waterproof mobile electronics, and they've been selling the KPW since May 2013. They also sell a number of tablet and mp3 players, in case you're interested.
