Yep one thing in this discussion is that people have no idea how to read memory usage. A 4GB set of videos that are memory mapped will use a few megabytes of ram as the current portion of video is paged in. It will show 4GB of memory used in pretty much every tool. Chrome suffers from this as browsers work with lots of media that may or may not need access as the page is scrolled around. Using the mechanism all OSs have to deal with this (memory mapping) will report GB of ram used. But it will still be responsive! It's not actually using that much RAM!
I see so many comments along the lines of 'chrome reports xGB of ram usage when I open tabs. You can't get by with 8GB of ram!!!!' yet the computer will be running smoothly. Just as my old iPad with 256MB of ram runs smoothly with those same tabs open in chrome.
You might need more than 8GB but please don't try to claim people can't do the basics with only 8GB. I have an 8gb MacBook Air as a lounge PC. A PC used for the basics when I couldn't be bothered firing up the big gaming rig. Unsurprisingly the 8gb laptop is better than my still perfectly capable 256mb ram iPad running the same apps although the iPad was still decent at the role in any case.
The claims that 8GB is completely useless and can't even do web browsing because Chrome shows 8gb ram usage is so obviously stupid and false. Many are probably reading such claims on a portable device running the same browser with less RAM. Yet media and even tech sites are posting this crap repeatedly.
