Comment More I think because Lenovo quality is much higher (Score 4, Informative) 41
My company was recently acquired. We develop using virtualized environments on high end laptops and we're using Dell core i9 machines with 64G memory and a 12G GPU for AI work.
Several machines failed within a few days due to catastrophics NVMe drive failures. Then we had cooling fan issues where the fan would run away and eventually the bearings would fail.
They used a wide-screen aspect ratio screen despite no high end user wanting this, where a narrower and deeper screen would be much more useful.
Our new owner uses Lenovo devices so we replaced the Dells with Thinkpads having a very similar spec. They have sensible aspect ratio screens, are smaller and lighter despite having the same 17 inch diagonal screen size, and we have had no hardware issues whatsoever. At home I have a Lenovo Legion 5 which has performed flawlessly for many years.
A few years back I had a Dell machine where due to the use of incorrect bonding material, the BGA mounted GPU was guaranteed to fail after a certain number of thermal cycles. Dell never advised owners or made any attempt to compensate them, as far as I know.
So it seems no wonder Lenovo devices are selling well. They're just good quality machines
