The apple pen, touch recognition, palm rejection, and 120Hz + low latency are truly spectacular. I don't want to say flawless, but that's purely on principle, I can't think of a single screwup. Even my (employer's) macbook pro has a palm rejection failure about once a week, which is very good, but the ipad is better still. The base OS and websites have silky smooth scrolling, ditto for PDFs, even gnarly text book PDFs with scribbles everywhere. The pencil is super accurate, it has no problems hitting 1x1mm (or 2x2mm maybe) badges in LiquidText, and the size is perfect. It looks too big, but it's smaller than it looks. Apple did a good job earning their Apple Tax on this one.
