my first one has been suse, it was pain in the ass to be honest.
additionally i just had a 56k connection and the modem wouldnt run on linux.
now im using ubuntu 7.04 and im happy with it, my old laptop runs xubuntu, my "mess around server" with ubuntu as well. even my mums pc is running ubuntu :p
in the meantime i tried mandrake, knoppix one time.....got damn small linux running on a 40 mhz pc with 16 mb ram or sumthing, it was very very slow but i got internet running
tested the latest fedora one 2 days after it was released, but it was really buggy.
