An anonymous reader writes: If you wanted to pinpoint the beginning of the PC era, you could do worse than to declare that it began when the January 1975 issue of Popular Electronics magazine came out. It cover-featured the MITS Altair 8800, the first successful PC, and inspired Paul Allen and Bill Gates to found "Micro-Soft." I wrote about the issue, which is now available for free in PDF form (along with every other issue of Popular Electronics).
