Gizmodo posted an interesting review of Sony's new E-readers. And they are not very happy. The Reader daily edition has a lot of features, but they say that the glare on the touchscreen is simply terrible. The pocket device (PRS-300) is said to be lacking a lot of features - such as an SD card slot, a dictionary or a search function.

LG are showing new ePaper technology, with a flexible 11.5" prototype. The display is also a touchscreen. We don't have a lot of info yet, beside this photo:

Pixel Qi (a spin-off from the OLPC project) has a display technology that they say will be ready next month (samples). The 3Qi is a 10" display that has three modes:high-res color LCD, low-power black and white and e-paper.

They say that the 3Qi will be produced during the summer of 2009.  They are also working on new kinds of displays, including on-chip displays (whatever that means, maybe microdisplays on CMOS?) and touch screens.

Bridgestone Corp developed their own color e-paper technology (called QR-LPD), that also supports pen-input (sing Wacom's pen input tablet). Bridgestone's display has 0.8 second refresh rate.

They have also published a short video of the new display:
