At my previous job I requested an upgrade from a 3 year-old laptop. Initially they approved it, but before ordering one they reversed and denied my request. The justification was they'd spent too much outfitting new hires and it was no longer in the budget, despite my request coming long before the interview process started for the new hires. To make it worse, the new hires were entry level and I had the second longest tenure at the company (~90 people).
Now I work somewhere that happily provides every technical employee with the latest maxed out hardware. The difference in amount of work accomplished is staggering.
