I was pretty happy with the T100 and the Vivotab Note 8 as my companion device solutions. I'd take the two of them with me on camping trips and leave everything else behind. For 99% of the stuff I do, they were a great combination.
The T100 is great for productivity, and I prefer the 8" format for most casual consumption. I picked the Note 8 because of the built in Wacom digitizer. I'd heard bad things about the reliability of it - but I've had pretty good luck with ASUS, so I took a shot on a refurbished one, figuring that the issue with the pen was probably what had been corrected.
Unfortunately there is a very well documented problem with the ribbon cable that connects the digitizer. Unfortunately, about 15 days outside of the 90 day warranty, the pen started quitting on me. It was weird. It would start working than disappear. I started restoring to factory resets - and it would come back every time, but eventually it would quit. I tried installing latest drivers. That would get it to work for a while, then it would quit again. I found all kinds of ways to get it to start working, but inevitably, it would quit. Then the network disappeared. In the device manager, it wouldn't even see it. The pen started working fine. I couldn't get the network to start working again. I found that putting it in airplane mode and bringing it out then rebooting would get the WiFi NIC to reappear, but then the pen would disappear again after a while. I could keep doing that... getting the pen to show up, no NIC - get the NIC to show up, no pen. It was a big hassle. I opened it up and played with the ribbon cable - and that may have fixed it. I haven't done a LOT of trouble shooting - but it seems to do the trick for most people, at least as a temporary fix.
So, I got sick of that, and decided to just pick up a Surface 3. So, that gets rid of the Note 8 and the T100. No need for either of them when the Surface 3 does what I want from both of them.
If the Vivotab Note 8 was more reliable, I would have stuck with it. Now I'll have the Surface 3, and probably pick up a Surface Pro i7 or a Surface Book i7 sometime next summer - and those will be my two machines.
I do have the Note 8 for sale for $125 with a Wacom Bamboo stylus ($100 without). The digitizer is "as-is". Working currently, it may never have a problem again, but it may. It is probably as simple as replacing the ribbon cable, something fairly easy for anyone slightly competent opening up their devices.
The T100 is for sale too. I'm thinking $250. Atom, Windows 10, 2gb RAM 32gb memory plus 500 GB hard drive in dock.
I'm willing to entertain offers on the T100. For $100, the Vivotab Note 8 is priced to move. A refurb is $175 if you can find one.
