The PCjr was both expensive and unpleasant to use. Its infamous chiclet keyboard was wireless, but the raised keys -- kind of like BlackBerry keys that overdosed on growth hormone -- were uncomfortable to use for basic tasks like touch-typing. And, in another burst of dubious inspiration, PCjr didn't come with a hard drive. Instead, programs were contained on cartridges that you plugged into the front of the device.
Kinda like the first Trash-80 CoCo's......
LOL
Hey, it also came with a cassette recorder so you could save your basic programs to tape. The only ROM cart I had was the videotex one that I used to connect to CompuServe with.
