You can find the Archos 70 in Archos’ store at:
The only model available for purchase is the 8GB model. There’s also a 250GB model priced at $350. However, that selection is currently greyed out and not available for purchase. As tempting as the price is, I’m going to wait to see if the WiFi-only model of the Samsung Galaxy Tab becomes available this month before choosing which Android tablet to buy for myself.
