From what I see, Longhorn looks incredible. However, I am disappointed that all of the .NET technical magazines we subscribe to are now 80% + Longhorn articles.
I am still learning .NET. I have approx 1 1.5 years of development left on our current project with .NET and I'd still like to see articles on .NET development. I am actually thinking about canceling our subscription for the next 1-2 years.
Yes, I know I need to learn Longhorn. But not at this moment. In fact, I have 4-5 current magazines laying on a bookshelf collecting dust as they contain 100% Longhorn articles.
