Well... the article focuses on the car nav units. I've started using my phone with Waze for car navigation and it works great. So much better than the Nuvi I used prior. But "Portable GPS Devices" are used for more things than car nav. As much as I love my phone, it is no where near as rugged as my DeLorme GPS. When I'm out in the woods hiking or looking for a geocache, I'm not reaching for my phone.
