Nick if you are anything like me, most of what you have read in this thread might as well be blah,blah, blah, blah,windows,blah, blah,memory,blah,blah,blah. Last pc I had by the time it got to 2.5 years old I used to have to switch it on an hour before I wanted to use it because it would take so long to do updates and whatever other mysterious things they have to do to keep working. My mac is now five years old and hasn't slowed down a bit.I just want a computer to switch on and work, not have to "maintain" it ffs. As far as I am concerned it should be like any other domestic appliance you buy, use it till it doesn't work anymore then change it.
