Uhm, maybe nobody wants crappy Samsung plastic if they can get a Nokia. Same as above, why all want Nokia to come to Android, if they have Samsung, HTC, Sony,…
And who cares if Samsung makes a shitload of money. I want a phone that I like not a phone from the company that makes the biggest money.
Naaaaahh. Dont get me wrong, if you just look at the icons yours might look fresh and nice but if you look on a big screen full of icons you will recognise the simple and cleaner ones a lot faster.
There are apps which allow you to place a tile on the startscreen and launch another app. But as far as I know not many apps are supported and only 1 app can show livetile information on these tiles.
Actually I think its not worth lookin into it beside placing some tiled pics on the screen if u want that.
