Not just desktops. I'm typing this on a 2012 Asus Zenbook, which did not have any hardware problems so far (unless you count that one screw that came loose last year). Even the battery is still going strong: `acpi -V` reports "design capacity 5871 mAh, last full capacity 5070 mAh = 86%".

Of course, chances are that any other notebook might fail sooner, and I assume that my careful handling has increased the longevity of the device.
