Modular phones is a good solution. There have been a few genuine attempts [0] - and a big win is for the environment too because modular designs are repairable. I don't much buy the "slippery slope" argument for not offering a basic voice only phone, because there is a large demand for it according to article which I take as the premise for the discussion. The reality is that one cannot make a smartphone "as dumb as you want". Well, technically I can, but I don't know many other people who have a x100 bench microscope and SMD soldering gear to rework chips. Hardware capability is the key demand here because one fundamentally cannot trust software as it is today. Also, even if disabled in the OS, many potentially insecure and power-hungry subsystems remain active. Modular phones will need to mature somewhat to meet these new needs. It's high time that physical standards for modules were solid, but in Europe we will see interoperability and environmental regulations make that a reality. Expect to see adding cameras, Bluetooth, GSM and memory be as easy as flipping in a SIM. The environment and all cellphone users will thank us for that.
