- Maintenance work
- System and application updates - they take a lot of time and attention (e.g. permission check on Android during application updates).
- Declutter and free space on drives (to download pictures from the camera to the computer in my case) or on Dropbox to get the pictures uploaded that my wife took with the smart phone.
- Delete spam or less interesting emails.
- Make secondary manual backups.
- Fix hardware defects (change old-age harddisks etc).
Be it end-user support or administrative support. Errors may happen during updates, some passwords might be expired while you have been away for too long without logging in, some features (after an update) suddenly not working any more as you expected or - after not using for a while - you might not remember well how to accomplish a task seldom needed.
- React to changes in IT world
In my case during the updates on my mobile devices I have seen that many applications do want new permissions regarding device ids and call information. So the first action was abort a lot of updates and search the internet for possible reasons and for options to restrict this alarming trend against privacy. Lately there were plenty of news causing administrators to take action, like the SSL heartbleed bug or other alarming information, e.g. leaked by whistle blowers (like Edward Snowden). Not to speak of more long-term changes like technology shifts (those do not happen just during a single vacation, but while reviewing the past year you might notice a trend that needs to be evaluated).
And now take the annoyances mentioned above and multiply with the amount of devices you have... - I fear the time, when even my washing maschine needs to download updates and doing reboots before it can start washing - super annoying...
As a child, one of the main reasons why I got fascinated by the computers, was the fact, that it can help you making a lot of tasks faster and more efficient. Nowadays you have to pay attention that the total cost of ownership with maintenance work together with the velocity of change does not outweigh the benefit of the automation.
