crippleware
n. 1. Software that has some important functionality
deliberately removed, so as to entice potential users to pay for a
working version. 2. [Cambridge]
Guiltware that exhorts you to
donate to some charity (compare
careware). 3. Hardware
deliberately crippled, which can be upgraded to a more expensive
model by a trivial change (e.g., cutting a jumper).
An excellent example of crippleware (sense 3) is Intel's 486SX
chip, which is a standard 486DX chip with the co-processor
disabled. To upgrade, you buy another 486 chip with everything
*but* the co-processor disabled. When you put them together
you have two crippled chips doing the work of one. Don't you love
Intel?
