New Owner of XPS13 - Any tips (for newbie) to get the best out of it?

Hi all,

I now own an XPS13 thanks to recommendations on this forum. I must say that I am very happy with the laptop. I am a relative beginner when it comes to laptops, and I just wonder if you guys have any "must do's" in terms of settings to tweak? Sorry, I am being very broad here, but would love to hear your thoughts and if you have any tips or tricks in general on this machine, or Windows 8.1 in general?


Thanks!
