Lear more about windows phone 7 development

I would like to ask you a question in this little article. Do you really read e-mails that are sent to you by different companies. I am not really talking about spam here but generally about the letters or e-mails sent by such companies that you have already worked with or bought something from their offer? I mean, most of the people never open an e-mail with such content so what is the point of sending it? Can you explain it to me as obviously it is too hard for me to understand. How is it possible? Recently I have decided to try to read a message like this at least once. It was an e-mail from the iphone company. Inside I was able to read that they have opened a new section of their website where I can learn more about the windows phone 7 development. I have decided that it might be interested and I have visited this website. The new section looks great and it is actually very informative. I think that it would be interesting to a lot of people to read it. No matter if you are interested in windows phone 7 development or not. It is well-written and I am confident that such knowledge will become useful one day. Tell me what do you think about it and whether you visit websites like that.
