Actually, the cost is US$ 25, a lot less than the OLPC and it has just two connector, one HDMI and one USB.
Here is the picture of the $25 PC:

And now the same connected to a screen and a keyboard…

This computer, created by David Braben a game developper, once mass-produced could provide a computer to any student around the World.
The computer runs Linux, has a 700 Mhz ARM processor, 128 MB of memory on an embedded SD card and displays decent graphics with OpenGL 2.

A partnership agreement was signed between Microsoft and Nokia. The mobile phone manufacturer put on Phone Windows 7 as the main operating system on its future products.
Nokia also has a special agreement that allows it to customize WP7 while it is forbidden to other manufacturers when they install it on one of their models. It will participate in the development of the system.
Android does not allow Nokia to differentiate itself from other manufacturers, said the CEO, hence the choice of Windows. A custom WP7 will allows.
Faced with the slow development of MeeGo and with a Symbian system which does not support the touchscreen, the choice of an external OS was needed.
From 1 April 2011, Nokia will be divided into two structures: Smart Devices and Mobile Phones.
The first, Smart Devices, will use both WP7, Symbian and Meego on advanced mobile units.
The second will address emerging markets with the aim of providing to all mobile phones at low prices.

New concept in the field of semi-portable desktop computer, the Revo (like revolution) from Acer offers good graphics capabilities for minimal configuration and
footprint.
Designed on the basis of the modest Intel Atom N230 and the powerful
graphics card from Nvidia Geforce 9400M, the Revo seems to be dedicated
to graphics for which it offers the HD 1080, a processing speed
acceptable for most games and as bonus a 3D controller similar to Nintendo’s
Wiimote. HDMI lets you connect to a TV or monitor, and thus turns it in fact into a
kind of console game.
The graphics capabilities of the computer are sufficient to run Vista and Seven.
Prices currently charged in the U.S.:
The most expensive comes with 10 games playable with a 3D joystick,
for example: Sonic Heroes, The House of the Dead 3, Midnight Club 2,
Heavy Weapon Deluxe, Crystalizer 2, Crazy Taxi III Crashday and Balance.

Nokia enters the netbook market, offering even the first model with a HDMI connector.

To do so, it is equipped with a new chipset for Intel, because architecture today is limited to a VGA connector, not practical to often connect and disconnect the computer to a larger video screen.
This model exploits the “Pine Trail” technology from Intel that provides HD video capabilities and combines the processor with the graphics card on a single chip. This gives the computer the “HD Ready” label.
Nokia is a company that supports Linux and ARM processor suitable for both mobile as SmartBooks. But it ruled that the technology was not mature enough and preferred to go into this segment with a more conventional Intel solution.
These features may still change, as stated on the Nokia site.
The computer will not be available before the end of the year.
