Never had a Mac before, everybody was saying they were fantastic. You'll see, coming from Windows, what a difference, they would say.
The first had some serious hardware failure which made it reset at random times. With time the resets became more frequent until it became impossible to use it. I gave it back to IT with the order to destroy it.
The second had the infamous keyboard. God knows how much I hated it. Random keys wouldn't work, but most commonly the ones you need more, like shift. Thanks Apple. Went to IT and told them to throw it in the bin.
This last one I got has the horrid touch-bar which starts the bloody Siri 3 to 5 times a day because my finger randomly flies by the up-right corner of the laptop (typically when I am looking for the backspace). I hate it. The network sometimes goes away, for unknown reasons, until I reset the network card. Recently, the screen sometimes shows some worrisome fast-disappearing black areas.
You'll see, they would say. Very reliable, they would say.
