It's fast - much faster than Google Apps - and has a far less cluttered layout.

Now they're billing you two years in advance at $55. Keep it, I will get my mail for free elsewhere.

A free email client which is quick to install, and setup one or more email accounts. The interface is very user-friendly when i compare to windlows live mail for example. Multiple add-ons available for greater customization and functionality.

It's kind of older. Probably competes well with an Outlook 2000, or Lotus Notes style interface. It's had some upgrades, but unless you are a Netscape or Firefox lover from yesteryear, it's just not common enough to be a modern email program.
