A while ago I bought a Surface Pro 2. Very nice machine, versatile, build quality, responsive etc. But it was just too heavy to use for any longer stretch of time as a tablet. Then Asus released their penabled Vivo Tab Note 8 and I jumped at the opportunity. I've had it for a few weeks now and unfortunately I come away disappointed, but I've also come to realize that this isn't Asus' fault, if anyone is to blame it is me, and perhaps Adobe. Allow me to explain. There is one reason more than any else I went after these devices. I write a lot and that entails a fair amount of research before putting fingers to keyboard. So I scan books and annotate them in Adobe Reader. For a long time I did this on Android versions, either in Galaxy Note 8 or Note 10.1, very functional and straight forward. Then I discovered that the Windows version of Reader XI had a feature called "add note to selected text" this puts a hidden note, with hardly a noticeable icon in addition to highlighting the selected text. When you hover the mouse (or pen) over it the note displays automatically. Now this is what I wanted access to in a portable package. Hence the Surface Pro 2 and the Vivo Tab Note 8. Unfortunately I didn't take the time to research the whole thing promptly before making my purchases. Turns out that the Desktop version of Adobe Reader XI doesn't play nice with stylus input and control. Selections "slide away", trying to select text turns into right clicks (and yes, I have experimented with settings in Control Panel), pen annotations are ugly and the text turns blotty (it should look like it does in OneNote). Now, the reason the devices aren't going back is that they are still useful, portable and simply fun to use, but the one productivity field I had high expectations for was never fulfilled. And don't get me started on the Modern version of Adobe Reader, this isn't even in Beta yet. So here is hoping that Reader XII will play more nicely with my pens.
