Thanks to Windows 10, little has changed on that front. 
I still have a T22 and a T30 collecting dust… but the T61 is still usable with an SSD and the Middleton BIOS hack (to give 3 Gb/s SATA that was gimped to 1.5 by the stock BIOS). My latest daily-driver laptop is an X201 Tablet (with an i7), and even though it’s over eight years old (bought used for $cheap), is still a very nice system. The pen-based tablet mode doesn’t do much for me, but I’ve found it useful on occasion.
