Well, obviously this is pretty late, but I figured I could resurrect this a bit.

As far as 2.2's update... there are things to like and things not to like. Actually mostly not to like. The Archos 70 definitely hangs more often with 2.2 installed, I have to force reboot it far more often than I had to earlier. I have a male microusb to female USB adapter, but I can't seem to get anything to work on it. I've tried keyboards, flash drives, mice... it's quite a bummer. The adapter works because if I use a male-male usb cable and plug it into my computer, the tablet sees the connection and asks me if I want to mount the SD card.

Obviously I had to re-install gapps4archos2.2 to get the market and other google apps on there. Sort of a pain but whatever.

The lack of RAM is really starting to stand out now. I usually have to go in and manually kill apps so the tablet doesn't come to a screeching halt.

I still stand by my original statement that if you want a casual device, then this is a decent choice, but if you're serious at all about it then I would look elsewhere.
