For the guys complaining about not getting more performance compared to last gen keep in mind that the 1065G7 runs at a much lower frequency compared to 8550U while giving better performance.
So the core is much better but the process is still holding it back.

Very thorough

So 2 years later, a whole new core, a much-ballyhooed (and much-delayed) 10 nm process ... and this performs almost identically to the Yoga 920 from 2017 with the i7-8550U. Iris Plus graphics is the only significant improvement.

Hi Mike, how long did it take to arrive? It says 2-3 weeks?

Thanks for a suberbly objective review.

I have the 4k version. A simple check with  camera doesn't reveal obvious pwm strobing. I bought it not just for the screen but as importantly for the 1TB SSD.

General impression so far is of a very nicely designed and built computer. My one, subjective, quibble is that the fight to make this machine as light as it is has led to the back being made of metal that feels thinner than the average beer can. It tends to flex and click when I handle the machine. A protective slip case is on my Christmas wish-list.

I bought my Yoga knowing that the higher performance display would drain the battery more quickly than the headline figures suggest. A full charge looks to give me around 7 hours of normal word processing, spreadsheet bashing, surfing and presentation prep. Acceptabl but not special. I have no view of what video display or intensive gaming might do to battery life.

My conversation with Lenovo:

Andersson Steve M.: Hello, thanks for contacting Lenovo Sales. My name is Andersson Steve M. (Rep ID: 2900729623). At the conclusion of this chat, there will be a brief, two-question survey, scoring from 1-10 where 10 is the best. Please be sure to ask about our flexible payment options!

Me: need c940 14" info

Andersson Steve M.: Welcome to Sales Chat Department. How can I assist you with your purchase today?

Me: 5 displays available?

Andersson Steve M.: Yes

Me: do any use pwm?

Andersson Steve M.: all of them

Me: notebookcheck says the 1080p glossy does not

Andersson Steve M.: Well, that is the information I have about displays

Me: i'm not even sure what it means. What does pwm mean?

Andersson Steve M.: Pulse-width modulation

Me: is that good or bad?

Andersson Steve M.: That is good because it improve the resolution and avoid you headache

Me: Have a nice day!

Note the level of English: ...it improve the resolution and avoid you headache

I was going to ask about whether the anti-glare was an etching or a coating, but after Steve's dissertation on PWM, I decided not to ask. I think it's just the Gorilla glass. Anybody have a better idea about that?

16:9, reflective screen, poor trackpad, bad built quality... I'd still pick XPS 13 2in1 over C940.

i7 configuration is not available in Japan. Sad.

What about the 4k model; any chance of a review? (I'm mainly interested in whether the 4k display uses pwm).

How is this different from the Lenovo s740 14iil (the i7 1065g7, 16gb ram version)? Are the only real differences the speakers, the touch display and the ports or is there something else?

You do get the updated Iris Plus Graphics, in my opinion with the better quality silicon is worth the $150, ultimately a personal decision depending on your budget.

hmm at 1st sight they are the same. better binned, a bit more frequency, so exactly like i5-i7 before or ryzen 5 ryzen 7. id say it worth 50 extra usd. maybe. 150-200? no way.

Do you think the  i5-1035G4 with 16gb of Ram is much slower? Or does it make any remarkable difference at all? Thanks for your help.. im still undecided which convertible to get for university

i was thinking..what the hell is wrong with those stickers?
CORE I7 @TM (R)  all that stuff. isnt it anti-consumer? who and why need a sticker on his personal device?

It would be great to compare the C940 to the ThinkPad X1 Yoga. I can't find a good head to head comparison (nor for the C930).
