Outdoor segment users are more demanding, they always had faith and bought Garmin devices, if Gamin fails with Oregon 6xx it wont be a good sign for this company. Not sure how many customers will buy a Garmin outdoor again.
Outdoors devices are for people who need a reliable and trustworthy device. You can use a phone instead of a Nuvi, but you cant use a phone to go mountaineering in Nepal or to cross a desert.
