For me, a operating system is only a system that communicates the low level hardware with applications, and the peoples uses only applications, don't need what O.S peoples uses, we only uses aplications. Well, we are in app-centric "age", now it's needed to have Android or iPhone, or Windows for x86 to have access to the world. It's really needed? I think that is not true. I am using Maemo and i think that this system and with few apps, i have everything that i need for everyday.
Who here don't uses Windows 7?
