I have been using my previous iMac for over 10 years and its finally to the point, running super slow.i don't do much only YouTube, Facebook, eBay stuff as I m a stay home mom. but impatient, so I told my husband I don't want to wait for the previous computer to be able to browse the website so he got me one off amazon as the price is so much cheaper considering what functions I need. but after he bought it, I check the reviews and I was little concerned I have to say. but this is just taking the risk. all I need is fast speed which I m glad it gives me all I want. how many years its going to last? I don't know and I don't really care. as I m sure I will change one later.
