I regularly do winter caching using my Oregon's touchscreen with gloves on. I have to say, it sure beats the GPSr models I've used that have the regular manual buttons, which are generally pretty small. The Oregon's touchscreen "buttons" are fairly big, and they are sensitive, and I've had no problems getting the unit to do what I want it to do even with gloves on. I've found my Oregon to be quite practical. I really enjoy using it for caching and the paperless features are really the best out there.
I've had good accuracy with mine. While I've done no scientific study on it, I seem to be finding caches quicker with less "bee dance" than previous units. I haven't noticed coords to be really far off on vary many caches I've tried. I usually get down to under 10 feet. If the coords have been way off, this is usually true of other cachers trying to find a particular cache when I go back and read the logs, so I could make an assumption it's not my unit and more of a general cache placement problem. Remember, if your GPS is way off in accuracy when finding a geocache, it could be the cache owner's GPSr used during cache placement which is at fault as much as the unit you're using to find the cache with, so determining accuracy by how close you are to a cache placement is at best prone to a LOT of variables. You have to take any comments like this with a grain of salt.
I have heard many negatives about the CO and some rumors that Garmin may be dropping support for them, so I'd check into those threads and find out if this is fact or not before buying.
I rarely hear any negatives about the 60CSx. From what I could see, it is a real workhorse and what most geocachers around here use, and they all seem to love and have good things to say about their units. It was the other device I had narrowed my choices down to besides the Oregon of all the ones I looked at when making a buying decsion. I actually had one sent out and tried it before deciding on the Oregon. End use for me (mostly geocaching) dictated which one I chose, because the Oregon really kicks the 60CSx's butt on paperless geocaching. Now, on the other hand, if I was only doing a little geocaching and more regular hiking, hunting, etc., things might have gone a completely different way for me.
I'm not necessarily pro-Garmin, because I think pretty much every GPS manufacturer out there these days has some devices which are great, some good but not great and pretty much all of them can help you find caches. I looked at pretty much everything before narrowing my choices down. But I'm on a Mac, and Garmin has the best Mac support which made a difference to me, plus a number of other factors.

Perhaps the touch screen wouldn't make a difference with mittens on... have you had problems with fogging? How cold have you used it- -40?
Now on the Magellan side- IS it possible to transfer cords to it like the Garmin? I don't quite understand the whole thing, so dumb it down for me, eh? I seem to be able to find more Magellan where I live and cheaper too, and I liked ours.
