I have one of these Road Macs... Since I run OS 7.6 on another Mac (Quadra 605), I decided that I should be more "well rounded" by running OS 8.1. You are right that it slows down a bit (especially with the 64MB RAM), but still, it does its job.
One thing though... I have one of each, an LC NIC, and LC modem. LC being that it's a right angle Nubus card. My Quadra takes precedence in my mind, so it got the NIC, which leaves the modem card for the 6200. Good thing I've still got dial-up access too.
This Mac isn't really all to famous with me, although it has a nice footprint, and does its job when playing some Appletalk networked games with friends.
I also suggest iCab, although I don't use 3.0.3 (because it costs the monies), but if all you need is text based browsing, wannabe is much more stable and useful than Lynx or MacWeb. I do not suggest IE or Netscape (any version of either), they take too much resource, and those which don't have no good compatibility with the current state of the web.
Good luck, and have fun!
