@chen, regarding futur Lauta-like: - planning Dual-SIM (even standby) that would be wondeful for us travellers in Europe. - 64 bits CPU ? Even more awsome point if it's something remotely open-source ready that has chances to have upstream linux support one day (so maybe not mediatek). (Allwinner seems another popular chipset on linux project, but some of their SOCs variants are also problematic regarding GPL) - extension pins ? Like Jolla1's charging and I2C pins, or Fairphone2's USB pins ? Those have attracted a decent community of modders (see Dirk Van Leersum) and it would be cool if your project could similarly be hacked. (And gives an opportunity to all those unsatisfied customer that complain that your project didn't include their specific dream feature - like a secondary e-Ink display or whatever).
