I fully believe that combination works well. I also fully believe that if you asked a random person off the street to trade in their smartphone for two devices that only have partial functionality you would get told to go F yourself. I don't think it's a 'valid' option in 2025, and I would love to know what the average person on the street would say if they actually hear you out on all the benefits. I'm a 'tech enthusiast' I guess and a long time FOSS lover. I have been daily driving Linux for over 15 years at this point. I'm not sure if I would put up with two half-phones in my pockets all day everyday, and I know my friends would laugh at the idea. I almost purchased a PinePhone on more than a few orders from the Pine store but I keep holding off for thing to become stable enough to use the phone as a phone.
