Confused about which laptop to buy.


Nov 11, 2015
My budget is $1800 for buying a perfect laptop/ need are it should be powerful enough to handle high grade softwares like Matlab, AutoCAD,etc. And also it should be handy and comfortable to carry around(ultrabook).one of my concern is that buying a ultrabook leaves user with too less space ( < 280 gb),and most of the work say pics editing, files ,docs and prototypes gets saved in the internal i think going for a ultrabook will restrict myself from high memory tasks.please help me get out of this confusion.also suggest me some models.
