Whatever happened to local loopback in email?

This is a very funny find. Today the most common email clients people use are: MSN Hotmail, Yahoo and Google Mail (Gmail). The most important thing an email client needs to offer, besides being nice to look and use, is its robustness in sending emails even during the most busiest of times. So I did a simple sanity check - What happens if I send an email to myself from my own inbox? I used all the 3 clients and did the sanity check and here are my results:

Gmail: Instantaneously (The new mail counter next to Inbox increased the moment I hit send and this test was repeatable and it behaved the same way everytime I performed it)
Yahoo Mail: Almost Instantaneously. I repeated the tests and found varying results but it is livable
MSN Hotmail: The mail was cold when it arrived. It took a whopping 20 minutes to arrive

So my question to Microsoft - why are you guys choking Hotmail and making it the worst email client a person can regretfully use for the rest of the Internet era? Get over the clumsiness and make it more robust and active. Its after all a local loopback to my own inbox. Why does it need to make a trip all around the world and then realize that it was originally intended for the same inbox it left about half hour ago. Wake up guys, the new Yahoo Mail interface is going to kill you guys...For now I'm enjoying with Gmail and YMail. Good riddance to hotmail.
