Over the years since the first business microcomputers started appearing (which really means the first IBM PC) I have always noticed the the purchase price of a mid quality PC has remained pretty stable. This despite massive increases in both power and currency inflation since those early days. I find it fascinating that, presumably, the improvements in materials and manufacturing combined with the increases in volume since then seem to have almost exactly matched those inflationary pressures. I have been using PCs for development since they first appeared and this has generally meant using mid to higher end models. And these have always cost me in the region of £2000 to £2500 over a period of around 45 years.
