Librem 5 has a number of features generally only found in high-end phones, such as USB 3, dual-role port, DisplayPort alt-mode, high resolution video out and a discrete audio DAC, but its CPU performance and its video processing capability are those of a low-spec phone from several years ago. For people who want to buy a phone that supports convergence or a specialized security/privacy phone, the price of the Librem 5 is very competitive with the other options on the market.
