My first computer was an IBM clone powered by a 286 CPU with two 5 1/4″ floppy disks and 512K of RAM.  Today, I own a 2.53Ghz MacBook Pro with 4 GB of RAM, a 500GB hard drive, and a DVD burner as well as an eight-core 2.8 Ghz dual processor Intel Xeon powered Mac Pro with 16GB of DDR2 RAM and 2.75 TB of combined hard disk space!  We’ come a long way. baby!
