My T430s: would be nice if I can pull out better battery life (have two new ones) and has some occasional issues with the wiring for the network hardware kill switch. It's perceptibly slower on some pages, but only slightly (never bothered to figure out if it was the old WiFi or the CPU, an i7 for the time). It has some superficial cracks on it. It would also be nice to have USB-C and all that new stuff. But: with a screen upgrade (1080p with the ASIC card) and the best laptop keyboard I ever used and spare parts online galore and the potential at least to easily swap the BIOS and upgrade further, and perfectly fine and performant for the software development I do, it's close to perfect. Maybe a T430/quad-core would be nicer, but I'd rather just own my work computer (T470p, which is also close to perfect as well, but in other ways.)

So, it is rather funny to confirm again what some others might be thinking. The hardware is old and will have longer-term support issues, but for now and for a long time, I am glad not to think about having to get a new laptop for any use.
