In the meantime, there's been no sign of the fully open tablet ZaReason was reportedly working on last fall, and the widely anticipated Ubuntu Linux tablet is not expected to show its face until later this year. Open source webOS and Tizen devices are still in the relatively far-off future.
'We're Making It Happen'
What I think is particularly interesting about the Spark is that it's being marketed by the KDE Plasma Active community itself rather than one of the usual suspects in the profit-driven hardware world.
The current, "stuck" state of the planned Cordia Tab project is an illustration of the difficulties that can arise for open source efforts when working with traditional hardware makers.
"Finally we have a device coming to market on our terms," KDE's Seigo noted. "We are not waiting for some big company to give us what we desire, we're going out there and making it happen together. Just as important: the proceeds will be helping fuel the efforts that make this all possible."
This is definitely an exciting prospect; I'll post an update as soon as I learn more.
