My parameters were:
- AMD CPU
- possibility to install 64 GB of RAM; a factory option with 64GB soldered down would be OK (but I don't think this exists)
- Thunderbolt / USB4 support
- Metal / "rugged" frame
- not noticeably larger than my current 830 G5 (310x235mm)
With these parameters there isn't all that much choice left. In fact, I originally had another parameter, on-board GigE LAN port, that I ended up sacrificing.And to find devices matching those criteria - I can highly recommend Geizhals, e.g. for the above: https://geizhals.eu/?cat=nb&sort=p&xf=14285_64%7E1482_AMD%7E... . even if you're not in the EU, their index/filtering is fantastic (though be warned, parts of it are manually collected, errors MAY slip in. The USB4/TB data is particularly iffy. I still know of no better alternative.)
Since my laptop is my primary work tool, I do generally take out a 4-year int'l next business day + accidental damage protection plan ("CarePack" in HP lingo). I have actually had reason to make use of it on my previous laptop (8470p, spilled Coke into it) - no issues in getting that fixed. Due to timing (this was during christmas) they had to come back a second time after mostly-fixing it at first; some minor parts weren't immediately available (they did get it back to working). But, this is the extra service that costs +¼ of the laptop itself — I have no idea as far as "normal" warranty handling.
