I think that software developers that eat, sleep, drink, breathe the Apple / mobile world need to be careful not to let this define their worldview of the software market. As big as the Apple / mobile market is, it's still just a small piece of the overall pie.

Although I think the premise is wrong, but Al3x has a lot of valid points. There's a huge gulf between app store apps and enterprise products like Oracle. There are still a lot of companies in the B2B market that don't put pricing on their sites - even when their products aren't that expensive. Worse yet, some don't show any viable means of buying their product on the web site - not just "plans and pricing" but no clear "how to buy", etc. The visitor is expected to divine that they need to call the company. When I see a site like that I assume that it's a "if you don't want to contact us, you can't afford us" filter.
