My old Oregon 600 is not well. It still works, but there's a big black blot of dead screen in a faitly important place and the rubber on the back has a split in it. I'm aware that it's possible to buy a replacement screen and do a DIY job on it, but I'm not sure about the back. It certainly won't be waterproof in its current state.
I'm thinking about replacing it but I haven't kept up with what is current.
My uses for a Garmin are twofold: I like to plot a track on some software or a website (bikehike was always my favourite) and download it to the Garmin. Then I simply use it as a breadcrumb trail. It doesn't matter whether I am walking or cycling, that's pretty much the sum total of my usage.
I see that there are lots of Garmin watches around these days - at a price. I cannot envisage how my preferred uses would adapt themselves to a watch: the display would surely be too small for me to use it as a mapping tool - can you even load maps onto one of these watches? And if you are riding along navigating, you don't really want to be taking your hand off the handlebars for long enough to be making navigation decisions.
So I think I'm likely to want a bar-mounted/hand-held unit. I've always used AA batteries - the only two GPS devices I've owned are the Etrex Vista HCx and the Oregon 600.
Alternatively, has anyone successfully replaced the screen and the back?
