Archos has just announced a couple of Android 3.1 tablets, the 80 G9 and 101 G9 models. These devices are separated by the screen size, with the Archos 80 G9 offering an 8 inch display with a 1024 x 768 pixel resolution, while the 101 G9 features a 10.1 incher with 1280 x 800 pixel support.

The pair took off in Paris and these units have something appealing in common: the Seagate 7mm Momentus Thin 250GB HDD, that should kind of eat out of the battery life a bit. Under the hood we find a dual core OMAP 4 processor @ 1.5GHz and this is an ARM Cortex A9 we’re talking about. There’s also a full size USB port in the mix, flash support and HDMI output.

These models will work with a 3G WWAN stick and a pay as you go option associated to it. Expect a version with 16GB storage and microSD card slot as an alternative to these HDD-based slates. We’ll see the Archos models taking off in September, with the 80 G9 priced at $270 and the 101 G9 priced at $349.
