As SliTaz 5.0 will support Arm, I just open this thread to collect hardware infos for Arm desktop Mainboards.
Until now, there is Raspberry PI (now in revision 2), Via APC, OMAP4 PandaBoard ES and Kotron KTT30
Now thats the first one, which is a real desktop alternative with a good price.
ODROID-X - a quad-core ARM Cortex-A9 1.4GHz SoC, a Mali-400 MP Core (Samsung Exynos 4412 SoC) with 1 GB of Ram with a affordable price - 129 $ + 30 $ shipping - powerconsumption max 10 W
to buy: http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G133999328931&tab_idx=1
here are the first specs: http://www.phoronix.com/scan.php?page=article&item=samsung_odroidx&num=1
its a great alternative to Intels Atom and AMDs Brazos plattform, where you can be happy to run the computer with 10 W just standby (idle)
