Finally the Notion Ink Adam has cleared the FCC and the tablet will start shipping from Wednesday. The tablet from Notion Ink surely packs some punch with its almost unmatchable specifications.

The tablet codenamed Adam runs on Android 2.3 but will be upgraded to Android 3.0 or Honcycomb once the OS crafted specifically for tablets is released. However, Adam uses a customized version of Android 2.3 known as Eden, which imitates almost all the features of Honeycomb. Also, the OS platform Eden is expected to feature its own app store known as Genesis which is due for release real soon.

The primary loophole in the otherwise specification rich profile is the use of Android 2.3 which is considered to be an OS suited for smartphones rather than tablets, thus the Honeycomb upgrade will plug this caveat.

Notion Ink's tablet took almost 3 years in making and is expected to make an appearance this week for customers who have placed pre-orders. Also the company plans to pre-pone their February shipments to the last week of January. This would come as a reprieve for customers who have anticipating the release.

Here is a video demonstration of the Notion Ink Adam tablet as explained by the founder Rohan Shravan:

Motorola Xoom will feature Android 3.0 Honeycomb compared to Adam's customized Android 2.3 version codenamed Eden but Adam compensates for this as it supports Google Chrome OS and Ubuntu.

In terms of memory, Motorola Xoom will have 1 GB DDR2 RAM while Adam will feature LP-DDR2/DDR2 667MHz 1GB RAM.

When it comes to input features, Xoom has multi-touch capacitive touch-screen display, 3-Axis accelerometer compass, proximity sensor, ambient light sensor, Gyroscope whereas Adam will have multi-touch touch-screen, headset controls, accelerometer and ambient light sensor.

Motorola Xoom has a rear-facing 5 MP camera with 4x digital zoom and auto focus, 720p video capture at 30fps dual LED flash and a 2 mega-pixel front-facing camera. However,  Adam tablet will feature a 3.2 MP Swivel Camera which rotates up to 185°.

The Adam tablet will have Wi-Fi (802.11b/g/n) and Bluetooth 2.1 plus A2DP whereas Xoom will feature Wi-Fi (802.11b/g/n) and Bluetooth 2.1 plus EDR.
