The Spark is a new tablet based on the open source Mer and KDE's Plasma project. As someone who always did prefer KDE to Gnome (especially back in my linux-as-primary-OS days), I've been fascinated by the Plasma project so it's nice to see an interesting project making use of it.

The tablet has modest hardware:

7 Inch multi-touch capacitive screen

1 GHz ARM Cortex A9 processor with Mali 400 GPU

512 MB DDR2 RAM

4 GB Nand Flash Disk

Wireless Wi-Fi 802.11 b/g (3G via USB Extenal)

1.3 MP built-in front facing camera

HDMI 1080P Output

2 USB ports

MicroSD slot

3.5 mm audio jack

Hardware volume and power buttons

4 dimensional Gsensor

Battery: 3000mAH @ 7.4v

Weight: 355 grams

I'd take one for free/cheap to mess around with. I'm looking forward to when this begins getting into the hands of users and we can start seeing thorough usability impressions.
