I received this off Play around Christmas (unfortunately for my wallet). Maybe the excitement got to my head but after a few experiments with the Inkling it wasn't as good as I imagined.
The whole design and way it's packaged is flawless. The software is easy to install and use, along with changing nibs and packing it back up. It feels secure and well built.
It's let down by the accuracy. As a graphic designer I thought this would be a great substitute to scanning in masses of paper but when drawing detailed sketches and going back over areas it was unable to cope. For simple idea generation and doodles the Inkling would be OK, for anything detailed, stick to old fashioned ink.
The pen also feels very bulky and has to be held at a certain position which can be off putting.
