never thought I would say this, and I have had enough "discussions" with bloodline over the years, but I live my iPhone 4.  I think iOS is a really good polished OS.  I always thought everyhting being lockes down and uniform would be an issue, its not.
 
It means everyhting does just work , the same and as expected.  I have got to a stage in life, Im not that old, where I cant be bothered to install loads of thirdparty hacks and widegets etc etc.  I just want to use something.  
 
A lot of people I work with have android phones and there does not seem to be any rules about UI desgin or standard functionality. This needs to change.
 
RIM do not make good phones/OS.  If it was not for every compnay in the world giving them to their staff to check emails, they would have long gone.
