I'd like to say some nice things about Netronix, but to be perfectly honest they're not all that competent. The software and hardware of their stock designs aren't all that great. I have a couple ereaders running the stock Netronix firmware, and trust me, you don't want it. It's incredibly basic and does little more than show an Epub file.
In fact the only good ereaders made by Netronix that I've ever encountered were ones where some other company improved the hardware and did the software from scratch.
For example, the Pocketbook 360, which was released in late 2009, was based on a Netronix design that Pocketbook modified. Pocketbook also ported over their own software.
Or you could look at the Cybook Opus, the 5" ereader that Bookeen released in fall 2009. It has some details in common with the Pocketbook 360, but Bookeen refined the design. Bookeen also wrote the software running on it - twice, in fact.
And then there's the original Kobo eReader. Kobo did some amazing work to fix what is still a horrible design. They replaced the hard plastic D-pad with a soft rubber one, making it a lot more pleasant to use. They also added padding on the back, making the ereader just a little thicker and a lot easier to hold on to.
I am going to try to get my hands on the EZRead Touch, but TBH I'm not sure I want to.
