Assuming you will use the laptop for two years before selling it for 50% of the original price, the server will cost extra 1200 eur (24x50) during that period, making the Air + server option more expensive. Also, it's much more comfortable to have everything running on localhost. No network lag issues, no dependency on fast internet connection, less hassle, etc. Not to mention very nice 2880*1800 display.
