Are you or someone you know a Mac lover but brutally forced to use a PC at work? Don't fret or give up yet. Many firms such as Genentech are saying "no" to PCs and "yes" to Macs. And other firms are instituting BYOC (bring your own computer) programs that allow Mac followers to worship at work. Is this a trend that has legs, or have we entered the post-PC era where it doesn't really matter what hunk of hardware employees use?
