"Used it for about two years and finally plug the cord"
Poor and even not working search when the number of emails is big (like my case). It worked just wrong when the counter arrived to 10000 emails.
Outdated user interface
After two years of using it as my corporate email client, I turned it off, MS-Office is way way better. Is faster, the eye candy features are better, and it just works.
Thunderbird is a good option, but if you are an intensive email receiver/sender, it will render useless when you need to search your history.
