Performas are moving into the higher-education retail channels, just to confuse matters when you're buying a Macintosh. This means that colleges and universities can now compete with Big Bob's Computer and Vegetable Warehouse (our motto, "Buy a Performa, get a rutabaga free!"). The move also raises the question of what happens to the LC line, most, if not all, of which are identical to Performa models. [ACE]
Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
