In those pictures you can also see some common tablet features like on-screen keyboards, video chat, maps, and even augmented reality.
All of the Nokia tablets came with a stylus but were mostly used with fingers. The stylus was handy for web browsing - for example, on the iPad I have to zoom HN quite a bit before I can reliably hit the up/down voting buttons.
At some point Nokia even introduced a feature where the UI elements would sense whether you're using stylus or finger, and would size themselves accordingly.
This is because HN's design and HTML code suck. It's unreadable and inconvenient on laptops too.
