This page is a timeline of every Apple computer's introduction and discontinuation date. It also includes how much (in $US) Apple was selling it for when it was introduced, and how much when it was discontinued. Descriptions of the computer's historical achievements are also given when available. I decided to make this a seperate timeline for easier reference. Note, the discontinued date is not the date Apple stops selling them, but when it stops producing them. Discontinued Macs are usually sold by Apple from 6 months to 2 years after discontinuation. As usual, if you find any extra information or mistakes, please e-mail me.
