I see that Archos is well supported here with it's Arnova range.
They have bought out an Elements series of tabs, including the Cobalt, which has just been on sale in the UK for £49 and has caused quite a stir.
It runs native ICS 4.04.
It's a Rockchip RK3066 based tab, so may be compatible with some other ROM's based on this.
Root has already been achieved and users will now be looking for CWM, Custom ICS and hopefully a JB ROM that Archos have so far not released anything for.
