I love my Manta, the tablet is so thin, light with such crisp, natural writing. I looked at others before making the dive and am so happy so far.
Once I got over the learning curve of swipes, erasing, and file names, I'm good to go and use my Supernote Manta daily! It is where I keep all my notes for work, and I use it as scratch paper too. I'm very happy with it two months into owning it.
