My understanding is the correct, ergonomic distance your eyes should be from a monitor is about 1.5x the monitor's diagonal measurement. With 22" or 23" monitors, that's too far away for me to reach the screen at all, let alone work comfortably with one using touch.

For comfortable manual use, you really don't want a touchscreen to be any further away than your keyboard or mouse. That implies the maximum useful or ergonomic size for touchscreen monitors is actually pretty small.

>Maybe I misunderstood, or maybe it was someone else. (This is already a runaway thread and I am too lazy to dig through it for the specific post). IAC I have two very nice monitors which I do not want to replace. Also, I do not see touch capability being useful, or even supported, in the desktop apps I use. Also, I don't want fingerprints all over my screens ;-)

>>Did I say that? If I did, I didn't mean it. There is full touch in all editions of Win8. It will work on the desktop if you have a touch screen. There are a slew of touch-enabled tablets and laptops coming out. I haven't looked at desktops for a whilte, but I'll bet you'll find some there too.

>>>I asked about the touch interface earlier. What are you running it on? -- phone, tablet, desktop? I was told there is no touch capability in the desktop version.

>>>Regardless, you and Craig are giving me second thoughts about Win8. I have been in "someday over the rainbow" mode about it.
