I debated a long time between the Onyx Boox and the PB 302. I chose the 302 mainly because it doesn't need a stylus to operate. I'm happy with my decision but there are some things I don't like.
- Some of the 302s are pretty reflective. Mine is one of them. But most days I don't notice it.
- In direct sunlight, my screen doesn't completely paint. This is a problem with only some of the screens, I understand.
- PDF support is good, but not as good as in the Boox.
I've never had a problem with part of the screen being unresponsive. In fact when I want to move the screen up or down, I drag my fingernail along the very edge of the screen. As far as contrast, it's good enough. I wouldn't mind having a little better contrast. It's about like reading a cheap paperback. I read under a 19w CFL light and have no problems. I can read in direct sunlight as long as I shade the reader when I turn the page.
The pocketbook developers are constantly releasing new firmwares. I'm pretty pleased with my reader, especially with the latest firmware. Right now I think the Boox might be the slightly better buy especially if you don't have a problem with the stylus.
