I paint, so I do use them often (with a pen though), but as soon as the drawing is done, I gladly embrace the mouse again.
Windows 8 had a bad UI in my opinion, although the Windows 10 start menu isn't that much better. I have yet to meet a person that uses the alphabetically ordered list of apps, which you cannot edit in any way. Not long ago I was in front of an old computer with Win2000. No, the advantages weren't just habitual. You can control Windows without a start menu and this is what I basically do now.
So what would I do with a tablet? More painting. What else? Nothing. Apple is awesome for audio applications, but with MacOS please.
Not even browsing the web is fun because you cannot write angry comments anywhere without getting even angrier with your input device.
Some schools suggested getting touch devices for learning. I nearly ripped all my hairs out. Sure, you could attach a keyboard an all and a unified environment is easy to maintain. But you want your kids to learn something and be creative, write a text here and there. Never think your children to be as stupid as yourself.
Flash is cheaper now but the damage was done.
Another thing I dont get is the convertable phenomenon. There are USB and Bluetooth Keyboards and Mice, why not let the user choose? Also I wonder what hold Synaptics has on the industry to force a crappy trackpad onto every device...
