Remix - I ordered a Garmin 450t from REI, in part because I had $50 in certificates due to expire. In the interest of acccuracy - REI didn't have these in stock when the sale became effective, so mine is back-ordered. As you point out, smartphones have glass touchscreens, and having used my smartphone for 2 years, environmental issues like cold, scratching, and DEET, are not an issue. This isn't to say all touchscreen manufacture is the same, but still. Also, since I have to remove my gloves/mittens off to use my 60CXs (I have 2 - one is a backup), that's not an issue.
Mostly I ordered the Oregon because of its larger screen size, not that I'm dissatisfied in any way with the performance of the 60CSx which I've used for 10 or 15 years. On a related note - this last winter is the first one where I've used Sanyo Eneloops extensively. The 7 years I lived in the Sierra aren't a comparison as it isn't nearly as cold as New England. The last winter I'd winter hiked extensively in NE (2004/2005) I could expect to put in a fresh set after about 6 hours. This past winter they never needed to be exchanged, despite several hikes with subzero temps, including the minus teens. My practice is to put in a freshly charged set before each hike, and recharge the old with a smart charger. With 30+ winter hikes this past winter, using different sets of Eneloops, I'm satisfied the performance is consistent.
If I'm satisfied with the performance of the 450t, I'll be selling one of my 60CSx models.
Finally - I found an online service (free) which does a fine job displaying a GPS track and generating useful information. You can toggle the type of map display. It's called Everytrail, and an example of a recent hike to Killington and Pico is here. I've also posted tracks at Wikilocs, but it doesn't have a comparable mapping feature.
I think you will be very happy with it. There are alot of features that improve it such as a faster but more efficient processor and higher resolution display, and probably many more adjustments and settings. Let us know what you think about after you have had a chance to use it.
Enjoy the long weekend!
