It is strange, but intriguing !
For now not liking the stiction of the ball, which should go away (i hope) with usage. Also the scroll wheel feels flimsy and it is inconsistent.
For now still adapting to it, but not sure if i'll keep it because of the mentioned.
my take is because it brings joy + may be some level of challenge, while making a build plus extra fun to type on something new, adapting a keymap to your needs etc after that
