In one corner, we have:
The Sony Daily Edition *claps*
Primary features:
- Annotation
- 7" diagonal screen
- 3G
- Landscape mode
- $399
Oh, and
It's actually available for pre-order!
And in the other,
The iRex DR800SG! Seriously, who came up with this name??

Primary features
- 8.1" diagonal screen
- 3G
- Software SDK
- *Eventually* annotation
- Supports multiple DRM implementations
- $449
The dark horse contender, which becomes more and more viable as neither of these products make their Christmas release date, is the
Que ProReader!
Primary Features:
- Multiple formats such as PDF, PPT, Word, etc.
- Fully developed software suite capable of annotation, highlighting, and a buhzillion other things
- 8.5x11" display made of plastic
So what would you pick? Would you just wait for the Que at this point? I'm a software developer, so the iRex's SDK is very tempting to me. But I feel like I should wait until all three are out...I'm just not that patient.
