My issue with article is that it makes arument that programming style is decided by the interface or the device which in case of a device like IPAD is totaly false!

Yes Thinking in Scheme is different than in C++ but Some programs are more suited to be written in a functional language. And that has no bearing on whether the device is an ipad or a PC.

Interfaces dont define the programming style to be used! Underlying Problem does! And thanks to Apple you cant use a FP language on ipad!
