anyone using m.2 ssd ? any issue with high temps? coz I read somewhere m.2 drives have issues with overheating and ppl suggest to avoid

same with me, I'm a programmer too, using Linux Mint most of the time and coming from Dell E6420 company's laptop.
Now considering illegear's laptop due to upgradability and great support.

for touchpad, in linux at least you can customize a lot of the touchpad settings using synaptics and xinput, much better than Windows

if not mistaken Z5 support optimus, did you setup bumblebee or primus?
