Gloss kills it
The rest seems OK.
It seems suspicious that somehow Ubuntu seems to have problems with that hardware. They may have used some very oddball components there. From the photographs it doesn't look like it was well designed, but appearances can be deceptive.
What I'd like to see are the results of the "coffee spillage" and "drop" tests. A device like this, which costs several times as much as a used Thinkpad better lasts a decade. Is the battery easy to replace?
So all in all it's just Dell slapping Ubuntu onto one of their stock consumer models, something which the buyer needs to do again anyhow since they probably want full disk encryption. It's probably just another alibi product so they can continue claiming that nobody buys their Linux models.
