I owned an archos 7. My main complaints with it were the TN panel that had viewing angle problems even held right in front of your face, the low resolution, and the lack of ram. I enjoyed the heck out of that device but I will NEVER own another TN panel in any device. I've had them in full size monitors where they suck, but nothing compared to the suck of having a hand held one.
I did really like the 7 inch form factor but now owning a 4.8 inch phone (GS3) I have portable completely covered and decided to move up to the not so portable 10 inch form factor.
I REALLY wanted a nexus 10 for the screen, specs, and nexusness (no OS BS), but I can't swing $400+ right now. The HD+ seemed to offer a great screen, enough performance, good battery life, but a lot of OS BS. After checking to make sure there was work towards CM on it and at least a working root and gapps, I went for it.
Now that I have it, out of the box it was basically useless to me for anything but web browsing and reading. Rooted and with gapps, it does everything I want it to, its fast, and the screen does indeed look great... although I'm sad netflix doesn't really seem to do HD on a mobile device

, but that isn't the devices fault.
