Just about everything in this size class has soldered-in RAM. If you're looking for an 8G sub-notebook, there's also the latitude 11 series -- which is quite a bit more capable than the Inspiron, and is available with 8G (though also not upgradeable) -- however, as it cuts far fewer corners than the Chromebook-like Inspiron, the price is substantially higher -- it's a much more serious notebook than the entry level Inspiron 11 series.
