The computer made a lot of things obsolete. For example, typewriters, carbon paper, and those calculators that printed to roles of paper.

Tablets won't make anything obsolete, let alone desktop computers.

"those calculators that printed to roles of paper" are called adding machines, or "10 keys". They are still around in a virtual form.

If you have a full size keyboard with the number pad on the right side, in Windows, you can open Calculator|View|History, and you have a digital adding machine right on your computer.
