Knackered after 3 years?
"...We know from our research that the age of much of the desktop machine population now exceeds three years, and that many organisations face considerable challenges maintaining the effectiveness of this ageing kit in terms of meeting business needs."
One of the two machines I am using right now is probably well over 3 years old. There's nothing wrong with it; probably years of life left in it. Bit dusty maybe, but that's about all. It's still reliable, shows no signs of clapping out, and is still more than fast enough to do my work. And I'm developing software on it.
I know technology marches on and all that, but the curve has levelled out considerably over the last few years (in practical terms). And most desktops are used to write emails, read and write some Word documents, look at some spreadsheets and talk to a database or two. Why is a three year old machine unable to do this today any less effectively as it managed three years ago?
