In a recent engadget article, Jon Fingas points out the following:
If you're planning to snag the new Mac mini and load it up with aftermarket memory, you may want to reconsider your strategy. Macminicolo owner Brian Stucki (among others) has discovered that the RAM in Apple's latest tiny desktop isn't upgradable, much as you'd expect with the company's laptops and the 21-inch iMac.

The Mac mini may be "wimpy", but it's more than enough for a huge cross section of the computer/apple-buying population.
I agree that 2 cores and 4 GB of RAM are sufficient for many people, though perhaps many of those extremely light users would be better served by a Chromebook, or even a tablet with a keyboard.
The problem I've noticed is users who buy entry level Mac gear and discover, after it's too late, that it's not sufficient for anything but light usage. Those 4 GB Mac minis run out of memory really fast, and start swapping like mad. I've seen it all too often.
My opinion is that Apple should increase their minimum RAM to at least 6 GB. The cost between 4 GB and 6 GB at Apple's volume is vanishingly small. There's no reason not to, except for misguided and extreme greed, in my opinion.
