I had a 2100 (I think it was actually a 2000 with the memory upgrade) in the early 2000s. It was a fun toy, but I remember most the challenges of getting to be play like a first-class citizen with my Mac†. I found it to be a cool device in the tinker-y way that I like messing around with Linux and Raspberry Pis, but at the end of the day it required more attention than was worth it.
†Excepting the iPhone, this has been the case for virtually every device I've owned. Palms (after the discontinuation of Palm Desktop), Smartphones prior to 2007, Android phones. 3rd Party vendors make a genuine strong attempt to make everything work, but first-class support really makes using a device normal, instead of a chore.
