There seems to be a lot of complaints from people running relatively recent Apple hardware. I don't really understand that - I mean, I get it with phones and the fashion thing and changing every year, but with laptops? There is simply no justification for someone running a year or two old MBP to spend this kind of money on an upgrade. Some will anyway, but it's not a logical decision.
For those running older hardware (I'm still running a 2008 MB!), pro users who regularly buy high-end kit for their work and newcomers to MBP...well, it's a wincing price but the hardware is great, it's still the best looking laptop by a mile, will retain decent value and will last for years. The price IS horrible, but it's comparable to other high-end laptops.
The same thing has happened with cars in the UK. Back in 2007 I bought a (then) new Civic. It cost around £16k. At change time three years later, I looked at the latest equivalent model and the cheapest was £20k. We are so used to assuming everything gets cheaper that we are surprised when things actually jump in price, but it's the way of the world sadly.
