Fountain pens can absolutely be practical. The only area where I don’t use them is where a permanent waterproof ink is absolutely necessary. In terms of pros, I find them much more comfortable to write with since I don’t need to use pressure on the page, and I like having a lot of choice in the ink that I use.

The only real con for me is that it is significantly more expensive than ballpoints. Fortunately, the claim that they can last more than 10 years is absolutely true, so you don’t really need to buy more of them (I do end up doing that anyways because I’ve fallen too deep into the rabbit hole).
