Used to need to pay attention to memory size, bigger memory, more money. Now, they all seem to have enormous memory, more than most folks can use.
Important that the "RAM", Random Access, which does all the in and out work, be adequately large. 10-15 years ago, ROM, "Read Only", the "disc", had enough, but manufacturers seemed lax on providing enough RAM. Cost factor, proly.
Just my thoughts, which may soon be thoroughly "tested" here...............imp
