> no headphone jack I am fully old man screaming at the clouds here, but what does this cost for Dell to include? I insist on a wired headset - telecommunications already barely works, I don't want to add wireless+battery problems into the mix.

Surely a usb c headset would work

Comments like this one remind me of all the people saying "China can't invent things, they can only copy the US" 20 years ago. Like, we're comparing a new Dell to a Mac released only 4 months ago. How did you feel about the Mac Neo then, and now? Is it also legacy hardware destined for the landfill?

3.5mm TRS jacks might cost 10 cents to include and then hundreds of dollars to service when they break. The issue is not the BOM cost.

> then hundreds of dollars to service when they break Can you explain what do you mean by that? It is quite rare to see broken trrs jack on a laptop, at least I have never experienced one, nor on walkman or anything getting heavy plug/unplug use. I thought it is an issue in reducing the cost to manufacture the case or something.

Does anyone even do repairs anymore? Swap a motherboard and that's it.

A more accurate title is can Intel (Linux/Windows) beat Apple? If you don't want to run Windows, is there even a choice? My issue now with the non-Apple computers if you want to run Linux it's really hard to predict how awful Chromium/Firefox will be. My work Dell Laptop is only a 3 year old CPU with integrated GPU (and unused Nvidia GPU) but Chromium and Firefox are both slow as shit just loading pages like Slack an…

You might want to try getting the Nvidia GPU working. They're several times faster than intel integrated, and browsers are a GPU-heavy application. Intel keeps trying to say their integrated graphics are finally decently fast, but that's only a select few special models. Their high-volume chips continue to have integrated GPUs that are barely fast enough for web browsing.

How are laptop GPUs these days in terms of energy consumption? My last experience was a while ago, but the battery drained fast with them active.

I like a good old headphone jack, but then the USB DACs these days are also super small and portable that I just keep connected to my wired sets. I have couple nice IEMs, and because my phone doesn't have jack, I've to carry around USB DAC anyway.

My (Razer Blackshark) gaming headset does that - the actual headset has a 3.5mm jack on it but the "guts" is a USB DAC with some THX stuff supposedly built in (questionable utility but most of the games I play don't support it anyway) - I figure they reuse the same headset components down the market and just don't ship the DAC, it works flawlessly under Windows/Linux so no real issues with it and I can use it with an…

Doesn't it use the CPU more because of the inefficiency of USB?

I mainly use Apple one on MacBook, and haven't noticed any CPU or issues with that. I've another one which has more power, can't say I use it that much so no idea about CPU, but I think because of higher power draw may affect battery slightly (prob bigger issue on phones).

Theoretically maybe (assuming it's not doing hardware offloading but I don't think that is all that common) but feeding a DAC with audio over USB isn't even a rounding error on one core and I have 16 of them (16C/32T) - iirc the actual DAC just takes PCM over USB 2.0 (Linux did tell me when I was curious), that's nothing to a modern desktop computer never mind a powerful gaming/development one.

Nothing for the desktop in the last couple of decades is going to struggle with that.

So... swapping $100 component for a $0.3 break?

Doesn't this make including the jack even less justifiable?
