Is it true? Android is definitely better for web browsing (even though it can be laggy). But Blackberry being better at email? Well, it's debatable. Blackberry is mainly aimed at Business users and Politicians and it is definitely more secure. But Blackberry phones aren't even that good if you put Email aside. Everything else is mainly garbage (which is why some Governments in some countries want to ditch Blackberry phones).
Android is mostly better at everything else except for Email (excluding Gmail). It's improving though, but Android is not exactly fantastic for business users and politicians but for normal users, it's definitely more suitable.
Why do they charge more? I am not sure.
