Spent 10 years at Bell Labs in the eighties being introduced to Unix in all flavors, I started using an IBM PC in the mid eighties. PCs have always been a single user no safetyI have been a mainframe systems programmer since the early seventies.
personal computer. It needed lots of add on software to overcome very poor security built-in.
Bill Gates in his avarice to dominate the PC market created and crowed loudly in front of
Congress that IE was part of the operating system.(This is a design flaw that has been the
downfall of his operating systems once the internet became hostile) Macs were OK but niche
until the advent of OS X, which is built on top of BSD Unix which was developed for DOD
DARPA to be safe in hostile internet environments. With the advent of Intel chips, OS X has
become the platform for all operating systems by running VMware Fusion under OS X.
I run XP and SuSE as virtual machines under VMware.
I switched from a PC to a 17" G4 PowerBook in 1993. I used M$ Virtual PC, but it was tepid at best.
Time Machine introduces to the end user the kind of backup systems once only found on
mainframes. Having Leopard embrace Sun's ZFS file system once again Steve Jobs moves
into the Enterprise arena.
I use a Mac Pro workstation, my wife has a PowerPC IMac and an Intel IMac and I use
my 17" Powerbook for presentations on the road. All are running OS X 10.5.1.
Oh yes I have a G4 Blue and White running OS 9.2
I strongly recommend Disk Warrior for inode maintenance.
The Mac Pro has four CPUs with an aggregate speed of 10.64 GHz with a terabyte of DASD,
I use a 23" cinema screen. The new Mac Pros have eight CPUs with 20+ GHz of aggregate power.
Using OS X is seamless and robust compared to any Microsoft system.
