I was sure I could get away with using something that's essentially a chromebook but I was surprised how well apk files replace any program I would have google "function of program .exe" I can search for the equivalent apk file. Really neat for editing videos as well, since the graphics chip is optimized for video encoding it seems that the programs use that to their advantage when exporting large files.
To really put the DeX to the test I'm uploading as many videos as I can edited and shot all on the s8/DeX. http://youtube.com/c/DennisAleynikov
Yeah, zooming is a fucking mess. To zoom in firefox, doubleclick the mouse, and while HOLDING ON THE SECOND CLICK you can move the mouse up and down to zoom. Neither control +/- and control + scroll wheel work.
Selecting text: click on a word and hold the mouse button down. This works exactly like long-pressing on a touchscreen and getting the text select pop-up.

But despite these, overall it's been a decent experience. I download torrents like I did on my PC, I watch movies. I have all my data with me at all times, which I like very much. I used to have a laptop but it was mostly furniture; with a small kid at home I didn't have time to even open it in most nights. And when I did have time, all I did was watch a movie or download a torrent, which is what I do with the Dex anyway.
I wish it would've had a USB 3.0 port.
