What kind of devices support ink?

Because on the ipad the ink experience is very bad. Used different pen's for ipad, but it's all the same as just writing with your finger on the screen. It simply doesn't work like the old tablet PC's used to work, which was way more closer to writing on paper.

The pen point is also this weird 0.5 cm thick thing, which feels more like using a crayon on the device.

Is there a sort of list of devices somewhere?
