"The device [101 Magnus] also includes a 400 mAh battery..."
"[101 Magnus Plus has] a 700 mAh battery."
Not very useful if the batteries only last a few minutes at best, unless they have some magic power management.
From reading Archos' press release, I think you mean 4000mAh and 7000mAh.
Horrible specs for the money. Those low end CPU's have poor software supports, as many developers, do not spend time adding proper hardware acceleration for them, thus you end up with a device that is only supporting hardware acceleration for probably 1 format.
there are not high-end tabletes like the ipad mini retina and the nouvel ipad air, even the Archos 101 Magnus Plus the higher, but they have good prices, the inly thing that consumers hope is that they would have good performances
