"...I refuse to buy a MAC as I can afford 3 or 4 PCs for the price of one MAC. I am not fond of Apple as I think they are an arrogant company. You have to buy their 2 year warranty program to speak to them after 90 days from purchase. I have an IPAD and an IPhone and neither thrills me. My wife loves the IPAD. I have used computers since my TRS-80..." Well,now that you have that out of your system...
