I am not - Apple's "Post-PC" vision was clearly not viable to me, despite initially out-selling the entire desktop industry initially. The "What is a computer" ads were cringe.
If I need to do work involving lots of typing, precise clicking or sitting for a long amount of time, I'd rather use a laptop (or desktop). And for less demanding stuff, the smartphone (which I'm already carrying everywhere by default) is enough.
The tablet sits in an awkward middle and I don't really find much use for it.
Which is something important to keep in mind when discussing VR adoption. A few people getting overly excited (or overly dismissive) is not necessarily a good predictor.
As a data point, I do own a tablet. It's mostly a mobile TV screen: a TV Headend client for broadcast TV, NewPipe for YouTube and VLC to a shared disk on a server at Home. Not having to sit in front of a fixed TV set it great. My TV is mostly forgotten in a corner of the living room.
I rarely bring the tablet with me outside home. When I do it's with a Bluetooth keyboard and mouse. Example: I'm on vacation but I need some sort of work connectivity in case nasty things happen. Ssh works better on a 8.4" screen than on a phone. That doesn't happen every year luckily. My laptop is larger, weights more and I'll cry if it breaks or gets stolen. Damage to the tablet will only piss me off a bit.
