My main laptop is still an ~7-year-old ThinkPad W530. I pretty much maxed it out when I bought it: quad-core i7-3740QM, 32 GB of RAM, a pair of Samsung 850 Pro SSDs (RAID1), Nvidia something 2GB, FHD screen, etc. I was thinking about upgrading recently and was leaning towards the T470 for various reasons, including seeing a few nice used ones available locally at "okay" prices... until I started to actually compare them! Based on the benchmarks I could find, I came to the conclusion that the performance of the T470 was no better than that of my old tank, the W530 -- and may have even been worse! Once I looked into the cost of upgrading the RAM on the T470 (as I tend to run several VMs concurrently) I decided I'd simply be wasting money "upgrading" to the T470. Additionally, I've got a T420 which, although even older, still performs amazingly well -- once it was upgraded to 16 GB of RAM and a 480 GB SSD. I've only got ~$150 in it and it'll do a fine job if/when the W530 finally dies. (The "upgrade" wasn't really a priority anyways, as I've got a beast of a workstation that I use 90% of the time.)
