   A PC laptop/notebook with 16+ GB RAM, Nvidia GPU for stability (hardware manufacturers seem notoriously bad at software, but Nvidia is relatively good if you ignore the Experience app that demands your data, and [training AI needs 50 GB VRAM nowadays but 80 GB is 10x the price of 24 GB](https://www.naddod.com/blog/why-isn-t-the-4090-used-for-training-large-models)), [Linux](https://www.youtube.com/watch?v=E_C3pgc1Iho) and [Wine](https://superuser.com/a/1191605/103551) and/or Windows 10 > expensive, hard-to-customize MacBook with MacOS (needs [Spectacle](https://www.spectacleapp.com/) and [HyperSwitch](https://bahoom.com/hyperswitch) to almost be as good as Windows 10), flimsy adapter wire and too many proprietary connectors. Preferably a 14+" matte Full HD (UHD is only useful at 23+" or equivalent in VR) [Super AMOLED](https://en.wikipedia.org/wiki/AMOLED) (except that [burns in](https://www.androidpit.com/how-to-fix-amoled-burn-in-on-android-displays)) [display](https://gist.github.com/CTimmerman/5c00b0d0c86043c935c53e99fbf722c5) with [Cinema 3D](http://www.lg.com/uk/press-release/what-is-cinema-3d) like the [LG D2342P](https://www.lg.com/hk_en/monitor/lg-D2342P) and [Thunderbolt 3](https://gist.github.com/CTimmerman/632df94fe038762d996dd821a82632df) ports like the [Dell XPS 13 9370](https://www.dell.com/en-us/shop/laptops/13-9370/spd/xps-13-9370-laptop) or [the superior in that role MacBook Air M1](https://www.tomsguide.com/news/macbook-air-m1-vs-dell-xps-13) (if like MacBook Pro [14"](https://www.youtube.com/watch?v=rq3Bqs3O8Bo), with excellent audio at the cost of being magnetic so potentially wrecking HDDs. [Apple hates data that isn't in their cloud.](https://www.youtube.com/watch?v=7cNg_ifibCQ)) or [customizable upgradable Framework Laptop](https://www.youtube.com/watch?v=0rkTgPt3M4k). Fingerprint scanners are nice as long as your skin is as dry as when you set them, and [adaptive brightness](https://github.com/CTimmerman/AdaptiveBrightness) using ambient light sensors like in the iPhone 12 make it nice on the eyes without manual brightness adjustment. 700 nits (cd/m2) is required for working outside on [sunny days](https://mytechdecisions.com/video/understanding-brightness-in-outdoor-displays/). 38 nits is barely visible in the shade, but too bright at night. Speaking of peace: Silence anonymous and noncontact numbers with "do not disturb" mode and only allow select groups, or set no tone as default and only assign ringtones to friends, or simply use [the silence function on an iPhone](https://www.businessinsider.com/guides/tech/silence-unknown-callers-iphone) or [do-not-disturb/priority mode on Android](https://www.androidpolice.com/android-13-do-not-disturb-priority-mode/).
