The new Asus Chromebook C523 comes with a full HD display with a touchscreen option, Intel Celeron N3350 or Intel Pentium N4200, and 4 GB or 8 GB of memory. This portable has no price and release date yet, but it should hit the market soon for around US$400 (considering the prices of similar models by Acer that have been around for a while).
