I want color though.

Lack of pressure detection makes it not suited to drawing.
I hope the Wacom stylus is more precise than on Onyx Boox 60 or Irex. I don't know how much DPI they have.

Seems that there's some degree of pressure detection, but we don't know how many levels there are.

Here's another video of the device. Sorry it's in Chinese. Seems a bit slow, and since it also appears to be a hefty beast...I am having more and more reservations about it.

It's using the same B/W LCD that was in portable video games in the early 80s. C'mon, ASUS, this is nonsensical.

Err... No it's not.

The 80's B&W LCD screens are monochrome - something you can find in the old RCA REB-1100 e-readers.
This is a non-backlit LCD screen similar to Pixel Qi technology.

Not sure I could handle taking large amounts of handwritten notes anymore. After years of keyboarding, I can barely sign my own name...and from the looks of the video, the same is true of the people playing with the device... <g>

True, but I'l love to have a fully-functional and color wacom-input tablet I could do art on using Painter! That would be cool!

Same, but some places you just can't use keyboard easily.

In meetings where the noise of typing isn't kosher, or jotting down notes on scrap paper while I'm cleaning data and running some analyses etc.

So I'd like robust stylus note taking features on whatever tablet I end up with. No interest in a monochrome tablet--I'd probably go more for a 2nd or 3rd gen Windows tablet once they get the battery life up closer to iPad levels.

Pixel Qi is multi-mode transflective.
The EEE Tablet has a screen more like what we have in the jetBook.

Thanks for the clarification - I'm a bit thin on the technical details behind it all.
What I meant to say by comparing it to Pixel Qi is that it's B&W and it's not backlit.
I thought jetBook was just a plain ol' LCD? So much to learn, so little time ...

I just found this thread going into the pros and cons of this technology.

On hindsight the LCD might be the way to go for annotation due to its speed. However, it is sensitive to lighting angle/quality and viewing angle which makes it less versatile. Given the relative importance of reading is more than writing, the fight might well go to e-ink, but it's dependent on individual reading styles. Personally I like to shift and move a lot, so the viewing angle and glare issue is a major one for me.

Yes, the jetBook is LCD. It's not backlit and it's grayscale. The IPS panel in the iPad is also LCD, as is Pixel Qi. The original Nintendo GameBoy had an LCD too, and so do nearly all digital watches and calculators.

LCD is a fundamental display technology that allows both transmissive and reflective designs. It is the turkey in the turkey sandwich, rather than the whole sandwich.

lickity quick 0.1 second page turns on a backlight-less TFT-LCD

Is page turn speed even an issue on a TFT-LCD?

Oh god, looking at my original "brick" Game Boy it's amazing to see how much LCDs have evolved from that low resolution blur-o-vision.

You have two kinds of LCD. One is reflective. Which means there is some kind of mirrory surface that reflects light back. The same as with paper (or e-ink). It doesn't have a backlight, because that wouldn't come through that mirror surface. Sometimes, such devices can have a "front-light" (the same as with the Sony 600), but this light is above the LCD layer, not behind. These screens are (almost?) always black and white.

The other is transparent. In this case, there is no mirrory surface and light from outside will pass right through the LCD layer. So, no reflection means visibility (as you can only see due to the reflection of light). These devices need to have a backlight to make things visible. In well-lit areas, this can be a problem, as the ambient lighting can be much brighter than the backlit, so you will have less visibility.

A third option is transflective, which comes from transparent and reflective. The mirrory surface in this case is not completely a mirror, it will let light through both ways. So, you can add backlight and you can turn off the backlight and still have a good contrast in well-lit rooms. This type of screens is already being used for some time in the high-end PDA's.

What PixelQi is doing is optimizing the transflective technology.

Yes, but that has more to do with processor power rather than screen refresh...
