If not then consider yourself not the true owner of the device you paid for. I spotted this e-reader in one of those technology exchange type places and for a few pounds I had a nice little device to add to my backpack of things I feel the need to carry. The device was in mint condition (probably due to someone finding its small format difficult to live with) and the guy at the shop asked if I wanted to buy any insurance as I was forcing my money into his hand. I told him that as soon as I got it back to my desk I intend to throw a seven on google and totally pwn it, I had no need for his pointless offer.
Getting in there is simple enough with a small Phillips screwdriver and a fingernail. The guts of the thing are interesting but for a quick hack focus on that handy mini sd card which you should definitely make a backup of before you begin mucking about with.
I used an sd/micro sd card adapter and my mac mini for this, if you need a hand look here.
There are many interesting modifications available online, from GPS to weather displays and I personally I really like the thing. It’s true there are likely better alternatives if you want an e-reader for reading books, the screen size is a bit limited but I loaded mine with a bunch of pdf manuals and walk-throughs for various complex networking tasks I do at the office that require more than just a login. As a pocket guide you can also SSH into accept no substitute.
The battery life is impressive and it even has a happy face icon pop up when you’re turning it on / updating etc. This adds to the impression of the unit as being a small but quality product, a device that (due to it’s pleasant disposition) has a soul and people pass it around and fiddle with it during slow spots in meetings. Having fully observed this behavior I intend on installing some sort of password sniffer and pwning those bastards as well.
