I keep the old eMac plugged in, even though the internal modem fried in an electric incident. It has nice internal stereo speakers, I got good music on it and can play some DVDs on there too.
Discovering I had nothing on the windows laptop to overlay type on a picture, I tried pulling up an ancient Adobe Photoshop. Just placing this type took almost two hours, plenty of restarts, and endlessly watching the little round palette twirl.
For quite a few years, the eMac has been a bit confused. Perhaps it never liked being adrift from the internet.
Its only connection to the outside world may be the USB connection and the still functioning DVD drive. Insert metaphor here.
