This is your chance to trade up. I’m quite sure someone out there could really use my XPS 13 with Linux, but it’s just too small for my aging eyes. I would like to trade it for something with a little more screen space. I am willing to take a loss in terms of value, but not in terms of power. I still need a solid quad-core (I don’t care if it’s Intel or AMD), but I’m not so excited about the ultra-fast SSD mine has. Let me suggest a good trade would be something like a high-end Inspiron of recent vintage, or a solid Latitude that isn’t too old. I’ll consider other brands. I need a 15″ screen with some RAM and drive space.
I’m willing to do some custom setup work on the XPS for you, like making sure suspend and hibernate work with Ubuntu 18.04. I don’t care about the OS your exchange laptop might have, because I need to run Ubuntu myself.
