i think that's why the crux of your argument is flawed. it's not just several years, you have no way in knowing or saying or proving how many years it woudl take for 8gb to be the new 4gb and 16gb to be the new 8gb.
don't get me wrong, i totally respect people for spending their own money
like i said, it's insane to think that people who purchased a top of the line macbook air will be left with a worthless piece of brick in a couple years. 8gb is here to stay for a while. and if anything, you should try to convince me why RAM usage will skyrocket if tablets are the new norm? Tablets are viewing the same website as computers right? If I would know any better, my ipad example was just to prove that people are focused on efficiency now instead of big jumps in performance.
of course, you can always get 16gb of ram and just get ramdisk 🙂
If you owned and upgraded a computer system in the last 10 years, you'd vividly recall how 1GB was (insane) .. then 2GB .. then 4 GB .. then 8GB .. Funny how 8GB is a standard (now) and has been for some time .. guess what's up next? 16GB.
Further, if you've followed tech in any way over the years, the improvements in hardware have all generally centered on storage and memory.... CPU tech is stagnant and if anything, having a core i7 processor (even the base model) is ridiculous for 90% of the users .....
So, the CPU is already insane...
then you are getting PCI-E (SSD) Fastest storage..
But then you opt for 8GB ram... That's the weakest link and by getting 16GB I ensured, in the coming years, that it wont be.
Tablets are the norm because instead of creating content, the majority of people just use thing clients to read content. Contrary to popular belief, Macbook pros have always held to be a professional's productivity machine. As I shareholder, I think its great that randos are buying quad core i7 processor based systems to browse the web... But, i'm sorry, a MBP will always be held as a productivity machine in my mind. So, it's hard for me to relate to someone who feels a tablet suits them just fine. I have never and probably will never own a tablet due to its clear limitations. Owning a 15" MBP that weighs nothing is how I compute mobile. If i need to access data and don't have it, I have an iphone. When I'm out and about, the last thing I want to be is connected.
Tech has become a fashion/accessory/bling to a lot of people who don't work in the industry.... Great for me as a shareholder, but no I can't relate to the mindset of someone who drops a couple of grand on a quad-core i7 laptop to browse the web. You've already over-stepped the bounds of what's necessary for you at even the base-level 15" MBP. Thus, debating w/ you about the future road map of tech and the necessity of 16GB seems like a stupid proposition.
