noones 'pissing and moaning', i don't mind them imitating the iOS keyboard design, it's a very well designed keyboard.
The only problem with this might be, that if you copy too much of the look and feel of another platform (even if you do it really well / really subtly), the average consumer might ask himself why he shouldn't go for the 'original' then anyways. (even though the great success of the Samsung Galaxy S, which is very clearly themed more similarly to the iPhone than to any other Android device, kind of proves me wrong

)
that's why i consider windows phone 7 so refreshing (in my eyes it is, at least). The design and flow of the Android OS would just be too similar to iOS for me.
