4 GB RAM limit

[Vasant]

What exactly do you need to run on your computer that 4 GB is not enough?  Granted, in the ARM world, the ecosystem is a bit more limited, but still basic productivity apps are available, and often, if you are not afraid of the terminal, some very light weight alternative to gui apps.  I certainly grant that many web sites can eat space, but there are ways to mitigate that.

I recently had to use Zoom. Not sure if it was available on my Ubuntu x86 and not having the time  before the call. I installed it on my phone with google play store and every thing worked smoothly with a nice icon on my screen. Later on I downloaded it on Ubuntu X86 and on the terminal did:
sudo apt install zoom-xxx.deb.

This is not user friendly , there is also no icon on  my desktop and I still have to go to the Zoom web page. This is the current state of application support on my latest Ubuntu 64bit installation. As you can see  even Linux X86 is a crap shoot as far as application support is concerned. Linux desktop on ARM is pretty much a dead end.
