Nobody will get close to replicating Apple's intuitive UI. They may have touch-screen abilities but that doesn't make them iPhones.
The funniest thing is that they all think that touchscreen means multi-touch...even more ironic is the fact that all those "pioneers" only appeared after Apple once more dictated how the phone market will be in the next months...they are all borndead to Apple, which leads technology and UI like no one else.
