My old hardware is kept alive and on-line
iPhone 3GS - charged and connected to wifi for old times sake
iPhone 4S - ditto (still used for Find My iPhone checks of missing family members)
Original iPad - ditto
Blackberry Playbook - ditto (still beeps for email)
MS Surface 2 (RT OS) - ditto (still very useful)
Windows Phone - ditto(lights up for FB Messages)
Several Sony PSPs - ditto
It goes on and on, dozens of them.
If my early-1980s Tandy Radio Shack Color Computers had wifi, they'd be online as well.
