I'm not saying i don't believe you, I'm just genuinely curious.
Edit: Looking at this thread, I have to say there has to be a cause and effect here somewhere. You have a million web-developers saying they need more than 8GB to use Chrome to surf web-pages and web-apps.
I'm pretty sure web-apps sucking that amount of resources was caused by giving web-devs machines with 8GBs+ of RAM to begin with. Giving them more, wont fix the problem. It will only make it worse.
As for a developer-anecdote: Almost all bugs post-shipping bugs I've experienced and had to fix, more than 50% has only been reproducable on low-resource constrained environments.
By super-specing your dev-environment, you are shipping bugs you cannot detect. You just don't know it.
