I see your point
I am talking about using the "Metro UI" version of IE 10 to access FB, Twitter and Google + - Not the desktop version of IE 10. It is slightly more touch friendly than the desktop version with Pin to Start, Tools, Refresh, Find on page, drag down to see open windows, swipe, etc.
I can zoom in and out if I want to use my finger to interact with the screen but that is not really my style.
Personally, I do not like virtual keyboards taking up 1/4 to 1/3 of my screen so I will always opt for a real keyboard for more than 140 character input. In addition, I am a stylus user. I have been using it for so long on Windows tablets (8 years) that it's just second nature to use it to navigate legacy programs (I'm talking about non Metro-ized Windows 8 apps) just like most people use a mouse or trackpad. I also use my stylus a lot on my Galaxy Note 2.
I use touch (finger) input only for large motor function tasks - swiping a window or scrolling tiles.
I am probably pretty rare in this respect.
I fully agree with you about the ability to share from different "Metro apps".
It is certainly not as prevalent as it is in Android.
