Got a study or three to back this up, or does this represent your own rambling opinion? A whole heck of a lot of loyal Blackberry users would disagree with you. Try administrating a unix box with a virtual keyboard and you'll likely go insane. No, swype won't help.There are three main reasons why phones with hardware keyboard and being phased out.
1. Hardware keyboards have been shown to be for people who have limited/poor hand-eye coordination. These people are a minority and studies have shown that these types of people require the extra sense of feeling a physical key to accurately acknowledge location where as normal people only require the physical movement of the thumb to accurately acknowledge a location of a virtual key on a screen. If you have trouble using on-screen keyboards then unfortunately you fall into this category of dysfunction.
2. On-screen keyboards are ridiculously faster to type on than the slow pressing of hardware buttons.
3. Hardware keyboards make phones massively thick which people do not want.
Im sure there will still be new hardware keyboard based phones for sale but only on mid-to-low end phones from now on.
