There's also Steve
Jobs: Touchscreen Laptops Don't Work, the explanation expanded in Why
‘Gorilla Arm Syndrome’ Rules Out Multitouch Notebook Displays. Rebutted in
the Slashdot entry Steve Jobs Was Wrong About Touchscreen Laptops
based on the Verge article Surprisingly, touchscreen laptops don't suck subtitled
How Windows 8 challenged the 'gorilla arm' — and won.
The last an
anecdotal account noting that "The touchscreen is a complement for mouse and
keyboard". The explanation translating to higher user cognitive load and likely
slower operation.
Even in Windows 8's desktop mode, which is
still difficult enough to manipulate with touch alone that you'll probably want
a mouse and keyboard, I'm constantly reaching up to that vertical touchscreen
surface to grab windows and snap them to either side.
The constant
back and forth away from a vertical screen alleviating gorilla arm syndrome
symptoms caused by holding your arms up constantly.
Now the question is
whether its all part of a grand design or simply fortuitous. You might need
look no further than the Verge article for insight.
