Pixel Qi is a screen tech that has been just about to hit the consumer market for a couple years, and it's been long enough that I've given up on the screen. I used to like this screen because it had a unique ability to have near LCD quality color while still offering a low power mode which extends the battery life.
But at this point I'm expecting that we'll see battery tech improve while LCDs get more energy efficient long before I ever get my hands on a consumer product with a Pixel Qi screen.
Pixel Qi likes to boast that their screen is on a dozen products, but that's not completely true.
First, the highest profile one, the Notion Ink Adam tablet, is no longer available with this screen. And at least one other device, the netbook from Sol Computers, is actually an aftermarket mod. I'm not sure that qualifies as a product. And then there's the XO-1 laptop, which can only be had in used condition or after it has been surplused out of a program. Thus it's not really available to consumers.
P.S. Don't mind me. I'm just sitting here pining away for my $800 Pixel Qi Netbook from Sol Computer. It's taking forever to arrive.
