My laptop has 8GB of ram, and I hit the wall fairly frequently. In particular, I tend to run a tab-heavy browsing style. Between that and Eclipse and whatever I'm puttering around on in Eclipse, it adds up. And it's not a 8GB limit, unfortunately. In practice it's substantially less. If I go above about 5GB in use, I start dropping file cache, and things slow down substantially. (It doesn't help that I'm not running an SSD currently.) Is any of this crucial? No. I could work around it, and did so frequently on my previous machine. But, if nothing else, the time adds up. And RAM usage isn't exactly going down over time. And that's not even getting into when I boot up a VM.
