IdeaPad 510 vs VivoBook S510 vs VivoBook X541UA vs ASUS F556

I am looking for a new laptop to upgrade from my good old Dell Inspiron i3-3110m before going back to school. I will be doing programming on the new laptop and I wanted to get something with good performance as well as something that is future proof, as I am planning to keep this laptop for a long time. Minimum specs that I desire: 

-15.6 Full HD display (1920 x 1080p)
-Kaby Lake Intel i5 processor (AMD isn't shipping Ryzen laptop cpus yet :s)
-8GB DDR4 RAM
-SSD if included, if not, that's fine, I'll do the upgrade to the 850 EVO 250GB on my own
-I barely do gaming but if a 940MX is included, why not

-Would prefer Wireless AC

-Light design, preferably less than or equal to 5 lbs.

-Will use the laptop as my daily driver

I narrowed my search down to these 4 models:

I can't find any reviews for the VivoBook X541UA. The VivoBook S510 looks gorgeous with the slim bezel. The IdeaPad 510 has the 940MX. The ASUS F556UA has an i7. What is your opinion?

I'd like to leave it to max 1000$ CAD tax in.
