They always say you should never let anyone borrow your fountain pen. The nib adapts itself to the way you hold the pen and write, so once it has adapted itself to you, if anyone else uses it, it risks upsetting the balance and not feeling the same.
I agree, a good fountain pen is a pleasure to use. I cannot find pleasure in tapping a key with a finger. Some keyboards make an irritating clacking noise, better keyboards are less irritating, but as an old fogey I have never yet found one that gives a positive experience like a fountain pen can.
