I seem to collect laptops, two which Id highly recommend being 13" Macbook pro (2015) (shame I could only afford 128gb ssd, 8gb i5 2.7 Retina) and a surprise find, also secondhand, Lenovo (IBM) thinkpad Yoga 260. The latter especially handy as , it had a built in Sim Slot, 8gb, 256 ssd, I5 and the bonus of a full HD touchscreen with pressure sensitve stylus.
Being a photographer this makes working with Creative Cloud apps much more intuative. Im at the low learning curve when it comes to development, but I think touch screen ability shouldnt be overlooked as a consideration, if only when it comes to designed logos, etc.
I do have an I7 surface Pro 4, but the lack of ports and flimsy construction (plastic hinges on an Aluminium chassis?? make its technical advantages a hard decision.
Looking forward to IOS11 for ipad pro 10.5.
