I tend to keep things a long time but may replace something before it’s reached the end. Depends on use. Quite often I hand down older stuff to my kids.

The XPS range is fantastic! I grabbed an XPS 13, 2 or 3 years ago (9350 if I remember correctly). Fantastic solid build quality and they perform amazingly well. No hint of slow down yet although it has been rebuilt several times. I use it for work and pleasure and it handles everything brilliantly.

Only annoyance is where the webcam is located - bottom left of the screen. I’m guessing the reason is to have a frameless screen but I’d rather have it at the top as usual.

Great plan and best of luck!
