One of my commenters on the post http://sunilgoswami.blogspot.co.uk/2011/09/why-iphone-sucks-fact-list.html shared this URL. I read the article and found that it was a good, sane, calm comparison of both OSes from a user who has used both.
So, I am sharing the link here.
Mind you, he says that he's satisfied with his iPhone now, but in time I am sure it'll get on his nerves so much that he will move back to the "good side".
This review also brings home the fact that no matter how hard I try I can't really point out all the problems with iPhone because I don't use one.
Also read the comments below that article, some of them made me laugh, talking about the camera on an iPhone..lol..hilarious!
