Just came across some comments on this model posted today at
the geocaching website by 'jneely11':
"I bought a 200 as my first GPSr and am having a serious love/hate
relationship with it. It's very easy to use (even for a complete novice
like me). The functions are intuitive, the controls easy to use and well
placed. The screen is easy to read and the built-in map is surprisingly
useful. However, the lack of a computer interface is much more annoying
than I ever expected. Additionally, the thing is somewhat flaky. It
routinely reboots (restarts, initializes, something). I'll be in the
middle of using it and suddenly it's asking what language I want to use
again. Once, so far, it lost all my POI's (waypoints, whatever). Just
boom, all gone.

Strangest of all, though, when I went on my first hunt, it was amazingly
inacurate. I mean .3+ miles off. I know because the first two caches I
tried were both in cemetaries and this thing was telling me I needed to
be out in the middle of a cow pasture. I went home and read about map
coordinates and datum. Different coordinate systems I
understand...datum, I don't. I did read enough to see that I should be
using WGS84 when it was set to GRB36. I tried changing it to WGS84 but
it wasn't one of the 3 kazillion optional Map Datum setings. I rechecked
several times and it just wasn't there. I sent an email to magellan, but
no response. After one of its "no extra charge" restarts, viola, it's
set to the previously nonexistent WGS84 and suddenly it's taking me to
within arms reach of the caches. I'm confused. Also, somewhere along the
way, it went into this strange "burn in" mode and printed a bunch of
diagnostic (callibration?) information on the screen. The users guide
had nothing on it I could find. It's actually done that bit twice."
