Ok, we’ll start with the simplest stuff: the icon. You need to know what icon to click on to open the program, right? So this is it. The blue bird wrapped around an envelope. This icon was designed by Jon Hicks of Hicks Design UK. It’s the same on Windows and Mac, but there is at least one difference. When new mail arrives, the icon of the Mac changes to this: This just lets you know you have a new message waiting on you.
On the PC, when you get a new message, you get a little envelope in the taskbar (near the clock). It doesn’t tell you how many messages you have, but it will let you know you have something waiting on you!
