Here we are with an "upgraded 'blue screen of death' ." The sad-face emoticon empathizes with the user. The original blue screen simply had no text or graphic display. This blue screen of death often results from a memory management issue for which Microsoft's operating system is
infamous.
Random Access Memory (RAM) chips hold information the computer needs while executing code. Eventually that information is no longer needed and should be flushed to make room for new information that can require a large amount of RAM's capacity. Sometimes old data is not flushed from RAM, thus "short sheeting" the RAM bed. Thus: the blue screen of death. (Restarting flushes the RAM.)
Mac owners are not immune to memory management problems; yet, these occur far less frequently than those for PC users. And when they do, the application they are using will unexpectedly quit. However, the Mac OS X operating system remains open and robust.
Consider that Windoze (the software) must operate over a number of different computers (the hardware). Hardware configuration can be different, machine to machine. The Mac's operating system (software) is married to the computer (hardware). This superior 'bonding' (if you will) provides a more stable user experience.
That said, Microsoft possibly has the best operating system for PCs when comparing prior Windows iterations. Linux buffs would argue that point as to the superior operating system for PCs.
PC sales are in a negative, downward trend until you include Macs in the mix. Macintosh sales continue to climb in a financially recessive economy. No surprise there when considering Mac's superiority in function and user friendliness. There is no price advantage with a PC once you add the features and peripherals that Mac simply comes with.
Switching to Mac from PC is easy.
