I had purchased a 60csx in June. Right after I bought it I heard about the 62 series coming out so I returned it right away. I had every intention of buing a 62s when it came out. But then Cabelas had the 450t for a great price and also had a $20 off coupon. It was on backorder but I was willing to wait. I bought it just to try it out with every intention of returning it within 60 days to buy a 62s if it came out. Everything I thought would be a reason to return the 450t and get the 62s turned out not to be, at least for me. I find the readabilty in bright sunlight to be quite acceptable. I can read it just fine. I thought I would like buttons better than touchscreen. But, I've gotten used to the touchscreen and really enjoy using it. The 62s is probably more accurate, but how much more? I find my 450t to be more than accurate enough for the geocaching I've done with it. Works great in the woods.
I did go back and compare a 62s side by side with a 450. I think the buttons would still be nice but comparing the screens I'd much rather have the Oregon's slightly bigger, prettier screen. Also, I really like the size of the 450 compared to the 62.
If I hadn't gotten such an great price on a 450t I probably would have ended up owning a 62s right now and have been extremely happy with it. I bought the 450t on speculation and it has really impressed me. I can't justify returning it and spending more money to buy a 62s. In conclusion, I don't think there's a bad decision between these two, get whatever one appeals to you more.
