Well I am writing this on a Lenovo T450, and it is as good as any model of laptop I ever had... at work it was Dell Latitudes we tended to get , and I still have a HP Elitebook, all Business Standard machines. The innards of this T450 are impeccable ... just like the IBM PS2 range I once purchased for labs. The only major change I have made was to replace the very poor LCD screen, with a Amazon sourced FHD .. and it is now a delightful machine.... best 80 euro on any part I ever spent.. The keyboard is very good.I'm not sure of that. Had to use an NHS Lenovo laptop recently (admittedly the cheapest most dysfunctional **** some inept manager in supplies could source and load with maddeningly slow crap like care notes etc). But the battery conked after two months, the keyboard has a cheap lifeless plastic resonance and the hard drive is glacial slow. My first desktop (back in the nineties) was an IBM 486, and that was ergonomically a very different beast
