However, there are also netbooks and notebooks around with a lot less memory than that. Tablets, while not currently one of Firefox markets, are also commonly seen with less than that. Lots of parents with second-hand computers, too, which haven't been touched in a while because it "just works". The overall attitude towards hardware is apparently "use it for two years, then throw away and get a new one", and yet underpowered computers surround me in a 5:1 ratio. I sometimes have to install plain old versions of software (Office '97 comes to mind) because the new ones provide 5% new features at the cost of half your memory. Maybe everyone else has techie friends that only care about the latest and shiniest, or maybe the rest of the world is rich enough to throw away perfectly good hardware just because they feel like it. But from my experience (as biased as it is), 4Gb is not an "only" situation.
