Electronics doesn't have an expiration date. I still have two of the Apple's earliest laptops (PowerBook 165C and 540C), they still work... nobody cares.
Technology has an expiration data. Those Powerbooks are obsolete.
... but they can still be useful or even required if you want to access old music and media productions.
I do keep old computers (Mac and Atari ST and SGIs) from the early 1990's afloat just to access old work. It is hard - and getting increasingly harder - to maintain computers that old, as semi-consumables like Batteries (NiCd), memory (SIMM) and hard drives (SCSI) all are now extinct (or even abolished) technology, and used parts tend to be in barely better shape than those you want to replace.
