It's been a tough challenge for a KDE Plasma Active tablet to materialize and it's also looking that way for the Improv ARM development board. When the ARM development board was announced, it was advertised as "shipping to North America and Europe near the end of January." A Phoronix reader wrote in this morning to remind us know that now at the end of February and there's still troubles in shipping out the Improv.
Aaron Seigo posted a few days ago in some MakePlayLive threads about the updates on the Improv coming forward, but there's no signals yet of a definitive ship date. The MakePlayLive product web-site is now advertising "Purchase today for shipping in March." The cost is still $75 plus shipping and now may finally ship next month as the Improv's SoC just becomes more outdated compared to more modern ARM designs.
This $75 (USD) ARM development board is based on the Allwinner A20 SoC with a dual-core ARM Cortex-A7 processor and there's 1GB of system memory. The hardware is far from impressive and really is only worthwhile if you really want to be about the "open hardware" spirit, like the modularity of the Improv, or appreciate the open community work going on within the Allwinner Linux community (largely at Linux-Sunxi.org).
The Improv is just one step better than the Raspberry Pi; those after more useful ARM hardware that's still Linux friendly and capable of much more, I would recommend the ODROIDs, CompuLab Utilite, or even the Samsung A15 Chromebook over the Improv for getting a much better bang for your buck with ARM Linux hardware. If you are after low-cost Linux hardware and going for x86 hardware, the new Intel Bay Trail NUC Kit is fantastic on Linux, among many other interesting Linux systems frequently covered on Phoronix.
