So im an EE student been using a MBP 13" but its just a bit to heavy and bulky for me to carry around all the time. I mainly use my computer for Matlab, a circuit drawing program, a txt editor for programming and the terminal to connect to micro controllers. I know any new MBA will be able to do this.. But will i be real hurt by the screen and keyboard size if i went to the 11" model? i went to apple store and tested the keyboard and it didn't seem that bad but using it for 5 min its way different than 8-24hours any programmers/students have any input in this?
