Lisa OS & OS X Lion 10.7

Feb 25th, 2011 by Atelier | 2

In 1983, Apple released the Lisa computer system. It ran on it’s own operating system called the Lisa OS. Fast forward to 2011 and Apple is preparing OS X 10.7 Lion for release.

So what else is new in OS X Lion? Marketing materials tout a new feature called Resume that allows applications to resume as it were when you last closed it. Another feature is Auto Save which automatically saves your work solving those annoying situations where a power failure causes data loss on open files.

These features are actually available 28 years ago with Lisa OS. Pressing the power button does not turn off the electricity to the Lisa. It instead sends a signal to the Lisa OS to save and close all applications and position of the desktop before going into a low power mode much like sleep mode on modern day Macs. Turning the computer on again, users are greeted with the same screen just as where they had left it.

It’s interesting how far technology has seemingly progressed. Monochrome screen to millions of colours, megahertz to gigahertz, kilobytes to terabytes and yet fuctionality remains largely unchanged.

    With the release of Mac App Store, wonder if we would be able to delete a program by just pressing the ‘delete’ button, or maybe it’s already implemented? If so, I’ll seriously consider switching to Mac.

    Generally most programs do not require an uninstaller like programs for Windows. On a mac, just drag the program to the trash bin to delete it. Simple.
