I can't figure out how I'm expected to use more than one digit on this thing at once. I usually type on a touchscreen keyboard with at least two fingers(either both thumbs, or the index and middle finger of one hand). The sliding action makes using two different hands impossible- I can't type many characters without having to move my thumbs out of each others' way. That won't work. This leads me to think that I should use one hand, maybe even four fingers. But then my entire hand moves position every time I have to slide, which means I have to move my entire hand back to the start position to use a different finger for the next character. The only way I can type with this system is using a single finger, and that's just way too slow.
