Vista was
released five years ago, Windows 7 two years ago, so how out of
date was your advice?
It depends on how much money you like to burn for nothing.
I have a core duo notebook, 2GB Ram, some 500-odd GB in the HD and use
it as my main computer, for designing embbedded hardware. I use ALL
programs you can think about (even Altium Designer) and have no troubles
with that. If you like to use office 1*10^128 and Windows 1384, it is up
to you, I use what works for me and I don't need to fork tons of money
to have "the newest crop" to show my friends.
It is a matter of usability x price. I'll buy a new computer (and hard
disk, and OS, etc) when and IF I feel the need, not because it is new.
