Apple, Apple, Apple....
This is actually an old story, but I still don't get why Apple behave like this... (I think I might, but I really really don't like it...)
JAMM has a fine article about the fact the Opera mini has been blocked from the Apple App Store. A quick Google search lists quite a few apps being blocked from App Store for no specific reason.
Everybody (incl. Apple) needs to wake up and realize that acting like this will eventually push users away. Right now they're still riding on a wave of WOW because of their cool hardware and beautiful UI.
