I'd like to take "upgradability" off the table. That's not Greenpeace's business, but it is for iFixIt.
You don't buy a car or truck with an expectation of upgrading the engine four years later - you buy the size engine you need when you get the vehicle. If you need greater passenger capacity later on, you don't keep the chassis and change the body from sedan to minivan.
Upgradability is an expectation that is fairly unique to computers. Upgrade a refrigerator or stove? Upgrade the power amp in an integrated A/V receiver, or the display in a TV or monitor?
The "I'll buy less RAM now, and upgrade it later, when RAM prices drop" can actually be wasteful - if you have 2 RAM slots, upgrading from 8GB to 16GB means you'll have a pair of 4GB modules to dispose of (not much of a resale market for those things). Why should Greenpeace support that? Same for HDD/Flash. Apple's "buy what you expect to need over the time you plan to own the device" approach may be hard on the wallet, but it's not wasteful.
"Expected useful lifespan" includes many factors - changes to the customer's needs and requirements, changes to the technology, durability/quality of manufacture, and expected lifespan of components.
In general, the same factors that make electronics products harder to repair extend the useful life of the products. The repair vs. replace decision can be affected by difficulty/cost of repair, but there's a fairly large percentage of the population that simply uses their stuff until it breaks. For them, greater durability means less waste. Now, difficulty/cost of repair may also dissuade some people from repairs. It would be interesting to see some solid research on this aspect of human behavior.
