I always buy new, and keep a computer 5-6 years. I paid US$3800 for my
P73, but I included a lot of things that others might not think
important. You can get a P73 for as little as 1700. In the past I've
paid nearly US$5000 for a computer.

Your C$3744 is close to what I paid in December. Mine included a 1TB M2
drive, UHD with Nvidia T2000, and the external Thunderbolt dock. The
dock is great, but a word of warning - it takes some serious configuring
under Linux; it doesn't 'just work.' But if you want to use your
computer at work and at home, getting a dock for each location will
really simplify your life.

True of most Thinkpads, but especially of the 17" models.

Yes, I agree that my battery life is not as good as most on the market
today. But if you buy a 17" computer chances are that you don't travel
with it a lot. Frankly, mine leaves the house only about once a month.

I use the proprietary driver; nouveau is not even installed. By
'proprietary' I mean the driver in the Ubuntu repos, not the one you
can download from Nvidia. I might add that initially I just used the
Intel graphics and only later added the Nvidia driver. And having done
so lshw -c video shows that both are in use - it uses the Intel driver
normally (easier on the battery) and the Nvidia driver kicks in only
when it needs to. It is totally seamless; I never know which driver is
You mentioned running at 200%, 150% and 100%. Are you sure that when
you run at, e.g., 100%, you are really running at 1920x1080? I was of
the opinion that it was always still at 3840x2160, but that objects
(including fonts) were scaled to different sizes. When I watch a UHD
video in VLC it says that the resolution is 3840x2160. But I've made so
many tweaks to the desktop that heaven only knows what I'm actually
There are dozens of settings for size in the desktop, mostly for
different places where fonts and/or icons appear.
