The comments I was replying to, we're talking about phones.
What you're talking about is another topic all together, thumb typing vs. ten fingers.
What I was talking about was a response to a previous post.
There are some full virtual 10 1 keyboards that do a fine job.
That's your personal taste and opinion.
"Full virtual 10.1 keyboards" are smaller than fullsized physical keyboards. 'Cramped' would be my adjective of choice. They also don't have any kind of tactile reference – you can't feel them, or the relative position of/between keys – except for the virtual (but not real) 'tactile feedback' – vibration – of touched keys on some devices. Which is a rather pathetic substitute. Virtual keyboards require much more concentration on both the keyboard and the display screen, especially for longer texts, than physical keyboards do. Consequently virtual keyboards are much more tiring and not suitable to e.g. a continuous couple of hours of work. Which isn't a problem on physical keyboards.
