Sure. The Sony example was bad, VAIO was much more expensive than I would usually buy, but this was during inventory clearing; I bought a refurbished 3000 series when 4000 series came out. (and the refurbished bit was mostly a bit of minor scratching), so it was less than half of the price.

The Medion story was what closer to what I meant. Only that brand had combinations of features that I deemed necessary. (more for work than for Private, since for work I often have quite large directories of test images). At least then, now SSD sizes have risen somewhat again.

That said, I think it really is a shame that various listings don't list free bays of a laptop. Then you could add storage only if it really was a problem.

Don't you mean "gezondheid" ?

Yup, except for Apple of course since it doesn't sell Windows laptops afaik.

Does it finally have decent LFN driver? That and commandline lengths are usually the breaking point.

Maybe if it is ultra portable I could use it to run our Windows CRM client. But I have my doubts.

Yesterday I did some benchmarking of FPC building:

- RPI4 (32-bit(*)) with SSD (not flash) 4 minute 5 seconds
- Ryzen 2600 with SSD 1 minute 2 seconds.

That is still quite a gap, and then emulation overhead on top of that? Brr.

(*) Arm 64-bit still works with GNU AS as backend assembler and thus is twice as slow as the arm 32-bit (or x86 32/64-bit) targets that do have internal assembler and don't have to write it out as text and then parse it again.

Yeah. I regard Win 10 S as Chromebooks. Fine if you need something ultra portable for some surfing and minor document work, but if you don't really need that form-factor a lot, it is redundant

There are many ways. Displays is the most common one (which is just passing a pointer to a record with framepointers btw). Trampolines is afaik more a workaround if you don't want to change your stack and parameter handling too much.
