Of course these models will still be supported and receive firmware updates for some time to come, but I am a bit surprised by this. The 450 has been incredibly popular, and the 600 series doesn’t really have all the bugs worked out yet. Plus, they haven’t exactly received universal acclaim.
Now granted, touchscreens have improved since the 450 came out. This is a unit that required you to tilt it properly to be able see the screen in some conditions. You would tend to do that without thinking, but it certainly wasn’t a good unit for fixed mount use.
On the bright side, this does mean there are some good deals out there.
RIP Oregon 450.
