I rarely use a handheld phone, so I don't plan on getting the Pine Phone Pro.
A friend lent me his Pine Phone (and I may buy it from him), but I haven't done much with it yet.
When I am out and about I use a #corebootbook for most of my text and calls.
When I am in the office, I make most of my calls with a Logitech headset. I use phone.com for my VOIP provider that has a good web based interface for texts and calls.
I do also have a Samsung S5 with @e_mydata on it that I use as a backup in case I encounter a problem with my laptop. The phone is in airplane mode most of the time.
