Iphone vs black bery or nokia Nseries?

i think iphone had the right idea but didnt follow through. The touch screen interface is really the way of the future because you can customize the interface to the application. On phone with buttons those buttons are always there never moving never changing. Also it's web browsing is really good although it doesnt support flash. However the iphone's closed file system make black berry a more versatile phone because you can do what you want with it. The future of sell phones is making them more like laptops.
