Yes, that appears to be from the N8xx. The N800 was contemporaneous with the iPhone so I don't feel this is an unfair comparison. It shows how Nokia had the notion of touchscreen UIs completely wrong.
I still insist it's an unfair comparison because the linux tablets were a minor sideshow to the symbian phones. Then of course it's a fair comparison in that symbian wasn't great either, but at least they didn't just minimally repurpose a desktop UI.
