In a nutshell: The Asus Transformer TF700 tablet and mobile dock are not mature enough to be used for productivity purposes (i.e. as a netbook/laptop substitute).
I would never have purchased the Asus Transformer TF700 tablet and mobile dock if I had known:
1) Android keyboard shortcut support in connection with the mobile dock is spotty, most importantly with "Ctrl + X," "Ctrl + C" and "Ctrl + V." (With some apps these and other common shortcuts do work, but not with all--including the Google Chrome for Android app, which is odd since Chrome and Android are both Google products!!!). . . . It would be nice if keyboard shortcuts could be made to work universally at the Android operating system level just as they work on operating systems not designed for mobile devices.
2) Text can be selected ONLY by using the touchscreen--no mouse-click-and-drag text selection using the mobile dock is possible.
3) Text selection in the (Chrome?) browser is only possible in textboxes, not on non-textbox sections of Web pages.
4) All apps display only full-screen (i.e. It's impossible to display two windows/apps side-by-side, which is not a really big deal when I'm only using the the tablet screen, but would be much more frustrating if I connected the tablet to an external monitor.) (FYI: "Floating apps" replicate SOME multi-window functionality.)
5) I'm frequently unable to enter punctuation symbols from the right side of the keyboard--or if I can, only after I press the key more than once, after which the symbol DOES enter, but on the wrong line.)
I have done extensive reading about these things on this forum and elsewhere and realize some of these things have partial(?) solutions. If you feel I should have mentioned a solution I didn't, I would be happy to have you say so in your comments on my post. Also, I will be contacting Asus/Android about these things and hope to post any solution I get from them.
P.S. On the positive side, a touchscreen is addicting!!!
