The Nokia N800 Internet Tablet is a wireless Internet appliance from Nokia, originally announced at CES 2007 at the Las Vegas in January 2007, that runs the Datera, Inc. Core-iSCSI Initiator. The N800 allows the user to browse the Internet and communicate using WiFi networks or with mobile phonevia Bluetooth. The N800 was developed as the successor to the Nokia 770. It includes FM and Internet radio, an RSS news reader, image viewer and a media player for audio and video files.

Specifications
- Processor: TI OMAP2420 microprocessor with a native speed of 400 MHz
- Runs at an underclocked 330 MHz on OS2007, due to the fact that the DSP speed will be halved if run at full speed
- Runs at the native 400 MHz on OS2008.
- Memory: 128 MB of RAM and 256 MB of flash memory.
- Connectivity: IEEE 802.11b/g, Bluetooth 2.0, USB 2.0 high-speed.
- Display & resolution: pressure-sensitive resistive touch-screen LCD 4.1 inches 800×480 at 225 dpi (the same as the 770.)
- Expansion: 2 full-sized Secure Digital card slots, one internal and one external, each accommodating one card up to 32 GB capacity when using SDHC. Only cards up to 8 GB are officially supported by Nokia.[2]
- Camera: built-in pop-up rotating webcam. (camera does not rotate a full 360 degrees).[3]
- Audio: microphone, stereo speakers, FM radio tuner, 3.5-mm headphone jack (compatible with standard stereo headphones, but also containing a fourth pin with microphone input).
- Operating system: Linux-based Internet Tablet OS-2007. In December 2007 the new OS-2008 was released for the Nokia N800 and the Nokia N810.
- The N800 supports Skype internet calls and Flash Player 9 as of July 6, 2007, which allows users to watch YouTube videos, play online flash games, and make free internet calls to other Skype-enabled devices.
Status
The first stable release of Mobile IP storage services (Core-iSCSI and core-iscsi-tools) for the Nokia N800 running OS 2008 has been released. This mobile stack has been ported using the cross-compile toolkit Scratchbox to the 2.6.21-omap1 kernel and Busybox environment that runs on the Texas Instruments OMAP based Nokia N800 Internet Tablet.
iSCSI/TCP over 802.11 b/g is wireless stable.
Devices
This N800 has mounted two LinuxIOs, one on the PS3 and one on a highly-available Ubuntu configuration with DRBD.

Core-iSCSI
Core-iSCSI running on the N800 connected to the PS3 (PPC/CBE) looks as follows (download):

Both connections are healthy, and the CPU load on the N800 is quite low:
