I've been reviving and factory resetting our old devices to prepare for donation, recycling, or e-waste. Pictured here is 2011's biggest bomb, the HP TouchPad.
One thing that's surprising me is how usable these older devices are. Still fairly quick and responsive. Completely functional hardware-wise.
It just comes down to the OS and software makers refusing to support older hardware. There's no good reason this stuff should wind up in a landfill - but it very likely will, sadly.
