Let's start with a basic question: Do you know the specification of your smartphone's RAM?
Most users don't even want to know. Most of the time the phones process efficiently, that is, we will rarely see the message “insufficient memory to open the X or Y program.".
Samsung does not seem to agree with me and Smartphone with 3GB of RAM! There are computers that only have 2GB and work perfectly, using any of our favorite operating systems.
For now are just rumors pointed by the SamMobile team, but this is expected to be a reality in 2013. Then we will see some users installing “traditional” Operating Systems on Smartphones. Then do not say I did not warn you…
