Everyone who has a phone or laptop probably used the operating system as a main factor for making your purchase (i.e., Mac vs Windows vs Linux, Android vs. iPhone)...So what phone or laptop do you own?...what is the operating system on your device?...be VERY specific...what was it about the operating system that made you choose it?...now that you have purchased your device, what is your evaluation of the operating system?...does it perform and think all the things you thought it would when you made your decision to buy?...are you satisfied with the security aspects of the operating system?
