I used to think the same.
Turns out they are a good alternative to laptops.
If you don’t need powerful hardware, then tablets allow to save space in the backpack, are way lighter and always have a touch screen, which in connection with a stylus is big deal for taking notes. Laptops with a touch screen, in comparison, cost way more (at least where I live they do).
Personally, I use it for studying and media consumption. It replaced almost all of my paper. You can also sign documents using those (depends on laws in your country). Inserting photos into documents is one thing you can’t do as easily with laptops as well.
And when I do need access to better hardware, I just remote to my PC at home.
You can sign documents with the click of a mouse on a desktop. The validity of a digital signature comes from an authenticated account, time stamps, and an encrypted key; not your finger tracing on a touchscreen.
SkyeStarfell already said it more politely than I was going to, but you can also sign things from phones. The point was that it doesn’t have to be a written signature so the tablet medium provides no benefit.
Not every digital signature is legally binding, I’m afraid.
In my country, there are 3 types of it. A simple one (login/password), unqualified (encrypted series of numbers), and qualified (same as unqualified, but encrypted using certified means by government). The last two are stored on a physical drive.
The higher the grade, the more legal power the signature holds.
When signing it by hand from a tablet it’s the same as signing it personally where I live. Which, unlike qualified digital signature, can be used for any document.
That’s actually something we need to get handled as a society. Unfortunately the justice system still runs on fax machines so we’re basically not viable as a species.
