Under business laptops, didn't check consumer, here's what Dell offers with 64GB of RAM and a 14" display:

It comes with 2TB of storage (NVME). There's some kind of discount on their site that brings the price down to $3739, but list before that is $5346. A 14" MBP with the maxed out processor and RAM (also 64GB) and 2TB of storage is $4099. So about $300 more than the discounted Dell. Searching all their laptops and only limiting it by RAM (64GB) they show me five options, the above and 4 more. The above is the only one cheaper than the 14" MBP, and all of them are listed with a discount. Ignoring the discount they're showing me right now (how long is this good for? EDIT: Through 15 November, so a month remaining at these prices) they all (including the above) cost more than a 14" MBP with 64GB of RAM and 2TB of storage.

Are there other configurations which demonstrate that Dell is actually a spec-for-spec better price?

Thats one thing that the "Apple Tax" crowd never mentions. Yes, you can get another brand for 1/5th of the cost, but the specs aren't even close for 1/5th of the cost.

For $5000 you also only get a standard 60hz 1080p screen on the dell

I don't know if I missed something, but the last time I configured a comparable device (the Dell XPS 13) the prices for storage upgrades were basically identically. The overall configuration ended up being 200€ cheaper than the Apple equivalent, so not really worth considering the effort it takes to completely switch platforms.

Thanks for the viewpoint l. I've been wholly satisfied with my old MacBook, though, and thus don't think the overhead of switching systems is worth it for me.

Just out of curiosity, which Dell laptop would you recommend? Ideally a 14", light, and with good battery life. (I'll leave the more technical specs up to you)

The Dell XPS series are good, either the 13 inch or 15 inch, they don't have a 14 inch version. You could also get something with an AMD CPU (sadly Dell's are all Intel), the Intel ones have lower battery life.

I had a 2015 XPS 13 and it’s mobo died. It was disappointing but lead to one of the best support experiences of my life with a technician coming to my apartment to fix it for me.

Then the mobo died again 2 years later now out of warranty :(

My 2015 MacBook Pro is still going strong though :)

I am used to MacOS, and find Windows unbearable. Saying this as a former decade-long windows-only user.

I don't own a Dell right now but in the past I've had good success with the Inspiron series.
