WALL OF TEXT WARNING - SORRY! :-D
Recently pulled out a fairly modern Dell XPS that had a great OLED screen to read this thread and it was having some type of software or hardware issue.
Booted up my old reliable Thinkpad T420 (bought it from a Russian kid in SF years ago who upgraded it with an SSD and 12gb of ram when it was close-ish to new - it even has Cyrillic on the keyboard since he bought it in Russia originally!!). Besides a few windows updates and requiring a new battery (25$ aftermarket) the thing works great.
Forgot how damn nice those old Thinkpad scissor switch (I think that's the term) keyboards were - it truly feels almost mechanical keyboard like with a lot of travel. Did anyone ever sell a thin compact desktop keyboard with these style switches ? I could actually see it being very popular with people who like very low profile keyboards (like Apple desktops come with) but want something with more feedback.
I considered briefly upgrading the mainboard and internals to something more modern (there's an aftermarket Chinese company that sells replacements) as I think the T420 is the last Thinkpad to have the nice keyboards and key layout. Then again it was handling everything I threw at it without issues (even plays 4K YouTube fine!) probably because it has a decent i5 CPU from when they still had hyper threading and dedicated Nvidia graphics (the old semi "Quadro" NVS line 4200m). So many little features on these that are unique - instead of a complicated backlit keyboard for example it has a little downward facing LED light on the screen that can be activated by a hot key and illuminates the keyboard nicely at night. It's not as pretty or fancy but I love the simplicity and the fact you can also use it to illuminate a paper notebook or anything else.
One thing that does worry me is that Nvidia hasn't released updated drivers for this ancient chip since 2021 and I suspect eventually compatability will be an issue. I did have to disable hardware acceleration in the latest version of Libre Office (on Windows 10) to get it to work at all. I noticed in the BIOS it has options for Nvidia Optimus (meaning it also technically has an integrated intel GPU - currently disabled) so maybe worst case I will have to one day rely on that.
Thing is a real brick and battery life sucks but I also forgot how nice it is to have so many ports - it has dedicated eSATA (still super useful with an external SNES cartridge like enclosure to quickly read internal 2.5" and 3.5" drives) and a slim card slot where I had added two USB 3 ports. CD player wont see much use these days but a dedicated full size Ethernet port is great and an empty (I think they called it Ultrabay?) slot means I could theoretically throw in another battery or some random accessory. Also has full size display port for modern TVs and displays and oldschool VGA for legacy stuff. There's a fingerprint read I've never used (wonder if this even works with modern Windows?). Forgot I had even upgraded the WiFi chip in this thing (no soldering!) so it was getting great internet speeds as well.
I will say the cooling and fan situation though really suck - I forgot how damn loud the thing is with the fan even at 2/3 speed. I remember re-pasting the heat sink years ago thinking it might improve the situation and it didn't do much. Laptop was hitting 95C under load at first but after a little tweaking in the BIOS and the 99% trick to disable Turbo Boost it idles around 45-50C and hits about 85C briefly for high loads.
Would love a modern version of the T420 with a nice 16:10 OLED, the exceptional keyboard, tons of ports and expansion and repair-ability, a modern cooling solution, and less power hungry CPU. I really don't care if my laptop is thicker or a little heavier - the screen size is what restricts what bags I can put it in and the 14" diagonal format is pretty ideal. 13" I find too small and 16"-17" is getting way too big. I kind of even have grown to like the thicker bezels in a world that seems obsessed with minimising them - they really don't add too much overall size and I suspect it must contribute to the durability of the laptop and screen in general.
And of course gotta love a good track point mouse! With the mousepad disabled and my thumbs on the track point buttons you can transition from typing to moving the cursor around without ever needing to remove your hands from then keyboard - always loved the efficiency. I've had Dell and HP business class laptops with track points that also worked well but Thinkpad always had the best feeling thumb buttons.
Seriously though - why are there no slim scissor switch external keyboards out there ?! A compact 87 key format one would be the perfect travel keyboard (bonus if it had a track point and thumb buttons)!
