Very interesting project. It'd be nice to see video of it in action and what use cases the author had in mind. A pic in a different post shows the 48k ram chip, and not far away is an SD card of 1 gigabyte - that's a dramatic contrast. The storage can hold the contents of ram 21,845 times over. If an 8GB laptop today had the equivalent storage, it would be a disk of 174TB.

The 6502 can't actually address more than that. The flash controller built into modern SD cards are also going to be significantly more powerful than the 6502. And I'm surprised you can even buy SD cards that small still!
Unless you use bank switching, which historically a lot of 6502 machines did use (e.g. Apple III/IIe/IIc, BBC Master 128, Commodore 128, Commodore CBM-II, etc)
Surely a laptop prototype based on such a tested and well-worn CPU with 48K of RAM would be cool, but shouldn't it sip power? Like shouldn't it last for like months on a charge? Or am I revealing my very meager and outdated understanding of engineering with only a bachelor in computer science from like 2004?
A 6502 is capable of most actual workloads people have, whose profiles actually haven’t changed much. Almost all of our compute goes to GUI and rendering stacks that decorate our actual work.
Specs:
* 65C02 running at 10MHz
* 46KByte of user RAM
* EhBASIC 22p2 with custom extensions
* eWOZMON
* Compact Flash for storage
* Built in battery (7400mAh currently)
* USB-PD Rechargable
* 10.1" Screen with 1024x600 and 256 colours
* WiFi Modem (based on this - https://github.com/dhansel/WifiModem)
* nanoSwinSID for sound (as well as beeps)

Because most people I know certainly have different workloads and need their rendering as part of the work, not to decorate it nicely.
But for keeping a distraction free digital diary, it might be a nice device.
