Side by side comparison video showing the Pixel Qi 3Qi LCD screen next to the E-ink based Amazon Kindle, next to the transflective Toshiba R600 and next to a regular resistive touchscreen tablet laptop. Comparing performance in direct sunlight, in the shade and in a dark room with and without the backlight.
Following the initial video that was released showing the Pixel Qi screen during the Computex trade show in Taipei, Mary Lou Jepsen, CTO and Inventor of the Pixel Qi screen technology, answers user comments that were posted on the Engadget and Mobileread threads (among many other blogs who linked to the first video) with users from all over the world commenting and asking questions about the screen in the first video.
Mary Lou Jepsen, CTO and inventor of the Pixel Qi technology, explains more of how the Pixel Qi 3Qi screen works, shows us a bit of how she works with her screen technology in her home lab, testing the angular performance in the OLPC screen and tells how power consumption can be saved further with a few motherboard modifications to behave like the OLPC laptop (turning off the processor and motherboard when they are not needed) and more.

Bob Morris, Director of Mobile Computing at ARM Holdings introduces the new type of ARM based products such as ARM in Laptops/Netbooks/Smartbooks, ARM based Android smartphones.
This is it, the revolutionary LCD screen by Pixel Qi that turns your netbook into a Kindle by the flip of a switch. As you can see in this video, thanks to Pixel Qi technology, your next LCD screens can now be very usable outdoors as well under the sunlight, in a very high resolution black and white mode and also keep a full color and bright back light indoors mode.
This is a demonstration from the first batch of the first working prototypes of this screen, and as you can see, it already looks amazing. Mass production of these screens are planned to be launched soon and should be available in any netbook (and later other devices such as smartphones) as long as the manufacturers decide that they want to integrate it in their products.

Review of the Archos 5 TV Snap-On accessory that let's you watch and record DVB-T (freeview) signals city-wide and country-wide for most European countries which already have good DVB-T coverage. It comes with a dual diversity antenna system that allows you to get the best reception for a mobile DVB-T receiver, it picks in real-time the best available signal while you walk around or move your device around when at the football match, at work, in school, on the bus, on the train, anywhere especially in densely populated areas which have good DVB-T coverage.

Review of the Archos 2 mp3 player, the current cheapest mp3 player with 4GB ($39), 8GB ($59) and 16GB ($99) having such a nice color 1.8" LCD screen for videos and pictures. It's main selling point is that it's much cheaper than the competing devices by Sandisk, Dell, and Apple's ipod nano.

The main goal of the OLPC, and thus, of the whole computer industry at this point, is to lower the cost of laptops by lowering the power consumption. The best way to achieve that, is to limit the way applications get full native access to the deep internals of the computer system. Intel’s X86 standard and Microsoft’s Windows OS were designed only for that multi-purpose backwards compatibility where the same unoptimized bloated software would work across thousands of hardware configurations with often full root access to the deepest internals of a computer system. For most of the applications that most people need, you do not need full native code support in third party applications. By limiting full native access for third party applications, you take care in one swoop of all the security problems that one has on Intel and Microsoft based PC and laptops. You basically make spyware, viruses, hacking and all of those problems impossible by design.
That is how Android is made. Android provides a totally sandboxed JAVA-based software layer, which only interacts with the hardware features through totally controllable software-to-hardware APIs. With Android on ARM, you have a complete shift in the way third party applications are run compared to X86 Windows XP/7, MacOSX and even most of those X86 Desktop Linux distributions that have been going around, including Ubuntu and Fedora.
The open source native Android Linux code hacking happens exclusively at the manufacturer stage. Which means, you want to have a manufacturer in control of everything, you want the manufacturer to customize Android for the very specific mass produced hardware in question, providing all the standard and non-standard software-to-hardware APIs for third party software developers to gain access to the all of the devices standard or special hardware features.
What you have backing Android is the worlds absolute best company in Google, comprised of the worlds largest concentration of PHDs and Engineers with the most experience in Web and computer technology. The role of Google with Android is to make sure that the native Android code works in the most optimal fashion with the most optimal hardware configurations that manufacturers are making for it. Google helps manufacturers prepare that Android native code customization for each different System On Chip, for each different variation on the ARM Cortex processor profiles by each of the industry leading ARM processor manufacturers among Texas Instruments, Qualcomm, Broadcom, Freescale, Samsung, Nvidia, Marvell and others.
If you want to change the default Android user interface layer and make it look more like the Sugar User Interface layer (which for XO-1 was built on top of an optimized X86 Fedora Linux installation), you definitely can do those changes and customizations. Those would come from the manufacturers, thus in the case of OLPC from the whole OLPC organization, in cooperation with Google or anyone else helping to create a more education-laptop friendly user interface. But Android applications remain the same, and appart from slight porting that can be required, all Android applications are designed to work in full screen mode, and management of multi-tasking, notifications, memory and processing power consumption, all those are managed the same way accros all implementations of the Android OS.
HP has just announced that they are working to support Android in future HP Laptops. Asus has also announced to be working on Android laptops. Look forward to Android ruling over all ARM Laptop implementations, at least for these where the lowest cost and the lowest power consumption levels have been achieved. Look forward to $100 Android ARM laptops. Look forward to the empire of Intel and Microsoft crumbling under the inevitable hardware and software revolution that comes with the XO-2 and with the whole industry’s shift to lower cost, lower power consumption using ARM and Android in all laptops.
OLPC is probably looking for a non X86 architecture for XO-2, probably ARM, where several providers can provide the processor. Using ARM Cortex, OLPC can use any of Texas Instruments, Mavell, Freescale, Samsung, Qualcomm, Nvidia and others, all interchangeably, independently of the deals that will be put in place. The idea being that having all these ARM Cortex providers being more or less compatible with each other, enabling minimal changes in motherboard designs to have them all be compatible, this enables competition in the processor market. This will more quickly drive the prices down much further. This is the only way you can optimize the interpretation of Moore’s law which says that you can cut the price and power consumption of laptops by half every 18 months.
There is a basic reason AMD is not too enthusiastic about this whole new low cost laptop market. The reason is written on the wall, everyones can see it coming, cheaper laptops means it will be much harder to find profits in the industry. AMD isn’t exactly having an easy time already as things are today, Intel’s profit margins and overall income have shrinked 90% in 2008 compared to 2007.
I believe OLPC should use Google Android with Sugar on top, and they should increasingly rely on cloud computing such as the recently rumored Google Web Drive service to store and share all the data on. With XO-2, you should much further synchronize the way the school servers synch storage, processing power and contents to and from the cloud. Basically what you get is an overly simplified Internet access terminal, one with a small ARM Cortex processor behind the next generation of even lower power and lower cost Pixel Qi screens. One that just relies on basic Google Gears for local content caching, and let most of the rest happen using the much cheaper cloud.
$100 laptops using ARM are possible today already. Chinese GPS manufacturers are making them already using uber simple Linux and last generation MIPS or ARM processors: http://techvideoblog.com/category/laptops/
This makes it obvious that OLPC can achieve a $75 price point on XO-2, consider also the advantage of using a dual touch-screen, is that ou can even more easilly mass manufacture exactly the same model for the whole world. Since all the different keyboard layouts and all of the local interfaces are simply going to be a software function of the touchscreens. Mary-Lou Jepsen has done it once already. She can do it again.
