the design seems attractive but is impractical to use, at least for me. It is difficult to find a good placement on the separate numeric keypad of the keyboard and mouse. The separation of the keyboard into my problem. I can well use the keys on the keyboard left half, with several fingers (without using probably 5 but it's like on a keyboard "normal"). As against the right keyboard half my problem. After several weeks of using the fingers still can not find the keys as easily as on an old keyboard. I finally did use it almost as a right finger which creates tensions and fatigue in his right hand. But the most troublesome is the key 6 with tiret.instinctivement I type on 8 thus underlining instead of the dash. In short I think that average users who are used to type with 2, 3 see 4 fingers of each hand will have difficulty finding the same fluidity as an old keyboard. If there is a tutorial to learn to type with this keyboard, I'm interested!
