OS X (Snow) Leopard System Profiler reincarnated as System Information in OS X Lion (via: OS X Lion: Reclaiming the System Profiler Application | TMO Quick Tip | The Mac Observer)

Not only Microsoft has the bad habit of removing or changing features between (for Apple often minor) operating system upgrades.
This time it is between 10.6 and 107: OS X Leopard, OS X Snow Leopard and OS X Server had a “System Profiler” application that would tell you all about the hardware present in and connected to your Mac.
It has been named “System Profiler” over more than a decade (actually it had almost 3 lustrums), bot no more: As of OS X Lion, this is called “System Information”, and has been redesigned.
Both quoted names can be easily found by using the Spotlight quick search (which I think is still one of the brilliant pieces of software in OS X).
