It should be obvious that making a comparison between this technology and a traditional, stationary keyboard serves no purpose whatsoever. I initially purchased it for my iPad, but after seeing how well it performed in this capacity, I started making use of it across all of my devices whenever I had a significant number of print jobs to complete. Because of its size, using it was initially inconvenient for me, but after some time spent getting accustomed to it, I found that I like printing on it. I am, on the whole, content with the acquisition.
