I disagree.
My job is doing outcall tech support. I come to your business and work on your machines, keep them clean, and running well. On an average day, I put my hands on twenty to thirty machines, and on some days its closer to sixty. Some are scratchbuilt, some are "name brand": IBM, Gateway, Dell, HP, etc. Some of the scratchbuilt ones are built by my company to the specifications of the client.
Many of my clients have 2k and XP machines in office settings. They aren't running much more than Office2k, OfficeXP, or Office2k3. I spend all day every day looking at these machines with only 256mb of RAM and answer questions about why the computer is so slow. Clean computers. Computers with no viruses, spyware, popup generators or adware. Slow. Invariably, the answer is, "you can run less stuff, or you can get more memory." Office users do not understand about closing application to free up RAM. They do not understand about GDI resource leaks. They don't understand anything beyond "its slow".
Naturally, you could get these machines to work comfortably in 256mb of RAM if you went through and disabled a bunch of services, trimmed a lot of OS fat, etc. However, these aren't machines run by tweakers, they're business users working business offices.
"Context", as you put it, is a wonderful thing--when its applied properly. In this case, the context is what's listed above. I stand by my minimum of 512mb with at least 1gb being the preferrence.
As an aside, the two studios of professional artists I support (one uses primarily Mac G4s and G5s, the other uses scratchbuilt PCs), are more modest than you might think: the only machines with more than 1.5gb are the rendering farm servers, which all ahve 4gb.
