You're incredulous that some software stacks might need more than 2GB of RAM to run?
In any case, those 40c/day come to ~$130 extra/year, with which I instead bought a used Thinkpad X220, which comes with a decent CPU, supports 8GB of RAM and weights about the same anyway. I simply don't get Chromebooks.
Well sure there systems requiring any particular resource level. Long before the requirement is 2 GB ram, one might wish to get that on a server if for no other reason than to minimize installation hassles. Clearly, preferences vary.
Do you develop on any particular project 325 days a year? That's hardcore.
