I'm writing from a Dell, a few years old. You'll notice it has NVidia 
video, and it works fine. I just upgraded from a 14.4 kernel to an 18.1 
and there
was no problem with the video--I was watching a Youtube performance a 
few minutes ago.
The Dells have a pretty good keyboard, but I'm using an IBM model M 
while I'm at home. No problem with the external k/b or external pointing 
a Kensington track-ball here.  I have also plugged in an extra external 
optical drive, with LightScribe capability--that works OK too.
I bought the machine from a refurbisher, and it came with Windows 7. If 
you get one like that and want to keep Windows, you should use Windows
to modify the partition scheme.  I used Linux, and I wound up with a 
small extra partition that I couldn't get rid of and have Linux work. I 
live with it--
it doesn't eat much! (OTOH, I don't know how to manipulate partitions 
with Windows, I just know it can be done.)

This is my second Dell--the other was quite a bit older, and Win7 was 
kind of slow on it. So you see I kinda like the brand. I have no 
financial interest in
them, tho.
