Old machines felt faster because the delays better matched our intuitive mental model of what should be difficult. Displaying a single letter when you type should be instant because that's conceptually a very simple task. Switching between open applications should be instant because you can already see them both loaded. Opening a new application can be slow, because that's equivalent to getting up and fetching a new tool from your tool box. If you wanted instant access to it you would have left it on your workbench (left it running).
