The Surface book from what I see will be a great machine for an ID student.
If you’re more on a budget consider the Toshiba Satellite Radius 15 P50W-C-10V.
Go for at least 8Gb RAM and a 256 SSD. Intel HD Graphics works fine, in fact I disabled my AMD card because the Intel card is more reliable particularly with Solidworks.
I always prefer to go for more performance and have a separate Wacom, it works for me as digital sketching is only a very small portion of the work that I do.
I have a Toshiba Satellite P50-B-10L for two years now and it is still a spectacular machine with 8 i7 processors, 16Gb RAM and a 256 SSD.
