I registered jroberson.net and set the mx to point at google. Then I set my google account to let me pop and send mail via smtp. So what I don't understand is why google does this for free? I'm not looking at any targeted advertising. They're just acting as temporary storage until I pop the mail. I may never use the web interface again.
Also, I'd like to take this opportunity to point out that google is the new microsoft which was the new ibm which was probably the new something else. What I mean is, exciting and innovative company becomes large and imposing and then no one likes them. I'm surprised more people haven't seen the writing on the wall. I speculate that after 10-15 years of declining popularity and utility microsoft will eventually become a respected, productive member of society again like IBM did.
