Re: Use for these
Love the concept, horrible work environment. Back to Dex , I use a similar approach here with my Android 6.01 tablets , one of which has a dead touch sensor. Plug in charger cable, mini HDMI and USB 3.0 hub. (Fusion5 108T and 108 in case anyone is interested.) It just works. I already have all that gear as I've been doing this with the laptop, although it is full HDMI so thinking about KVM box lately. The rhe real fly-in-the-ointment is dealing with NTFS drives of the USB 3.0 sort. I'm not happy with the Paragon apps at all.
For on the road, toss mini HDMI cable, 22,600 mAH battery, Bluetooth keyboard and mouse into my bag and off I go. The cable is the only thing added. I was impressed that the only requirement was adding one cable to the mix with these two really cheap tablets. I'm kicking the tires on Termux right now looking for field OS that's a bit more capable in than Android 6.0.
