In early 2018, before I had children and with much, MUCH more free time, I bought a used X61, plus a used X60 1400x1050 LCD, a new backlight, new internal stereo speakers, a new mainboard with an Intel Core i7-5600U from 51NB, plus new SSD, 32 GB RAM, and the original IBM logo of a X60 which was replaced by a Lenovo logo on my chassis. It's the exact same setup as mentioned here [0], except that I built it myself from the individual parts for cost reasons.

The board arrived from Shenzhen after a month or so. I then had to manually fit (including drilling away some parts) the X60 LCD into the X61 chassis, which was extremely stressful. But in the end it all worked out perfectly. This X62 has been my private machine for 8 years now, and I always travel with it. The display still works perfectly, the 32 GB RAM are still more than enough, and it is still very easy to get X61 replacement batteries on Amazon. But the best thing is the form factor; this thing is just so neat and small and practical. Also the quality of the chassis is incredible. Apart from many, many scratches on the lid, it is still in flawless condition.

I had a ThinkPad X61T for a while, and assembled a full set of accessories for it, but it ran hot, and I never managed to get Wacom EMR stylus support in Mac OS working (bought it to be a Hackintosh).

I really wish that there was an updated ThinkPad which supported the current generation of styluses (was looking at an x230T until I got my Samsung Galaxy Book 12 and Staedtler Noris Digital Stylus).

I still use an X60 Tablet for travel, mostly as a terminal for the machines at home. Original CPU is good enough for VNC+Wireguard. AFAIK, there aren't any CPU/MB upgrades for X60/61 Tablet. I still like it because of the 4:3 screen.

I upgraded the screen to the 1400x1050 with a new display panel from china, but I had to cut the front screen protector and remove the "oil". It seems a little bit darker without that liquid inside and dust particles entered in that space. I couldn't find any LCD upgrade for the CCFL lamp at that time and now I'm not sure it's worth the effort.

I'd love to see a working coreboot for X60/61 Tablets that can still boot DOS and WinXP.

I have three of those setups I’m finally building …less!!1 than a decade later. Very hopeful those rare displays still work

Reminds me of my X230. Nowadays, I only use it for CAN-Bus related work on my car, but it is so small, yet so well build.

That's kind of like my T430: https://danangell.com/blog/posts/my-t430/

I wish it could go up to 32GB though. And the i7 in there shows its age. But it's still usable with modern software!
