The specs are an absolute joke. Even my Sony PRS from 2008 comes with 64MB RAM and physical buttons.
This thing will choke on epubs with embedded fonts, if it doesn’t just plainly ignore them (which it seems like it will, since they’re talking so much about their own custom font).
Neat idea, but I fear it’s destined to fail. I also think it’s too small. The PRS-505 is six inches and I wouldn’t go any smaller than that for comfortable reading.
