It's relatively easy to figure out how to start using it, which is nice. The Inkling takes normal ball-point pen cartridges, which will be cheap to replace. I noticed that it didn't start picking up my lines until well after I had started inking, so I had to go back and re-draw some spots. It also imported some of my spots a little wonky; I was drawing a super-hero type commission and the dude's face ended up all kinds of messed up, so I had to re-draw a lot of that in Photoshop. I'm used to using Microns to ink with, which is a really nice, warm black, and the ball-point pen is more purple-blue black, so that was a real shocker. (Nothing a little Photoshop tweaking can't fix.) It also doesn't like it when you draw past what seems to be it's threshold of letter-sized paper. The Inkling would be perfect for something smaller, but not so much any big projects on bigger paper. (Granted, I haven't tested putting the receiver on the side as opposed to the top of the paper.) I found out the hard way that if you move the receiver mid-drawing, it starts it as a new sketch, so the last few bits of sketch didn't end up on the right file.
Overall, my first impressions of the Inkling are that it takes some tweaking and it isn't worth the $200 price tag. At least, not yet! I plan on using it more to get used to it; I haven't given up on you, Inkling! Here's a preview of what my first attempt at Inkling drawing looks like:
