Smart ppl make the maximum use of phone, they will need the smart phone. Samsung phones (except windows, android) cant stand before Nokia (Symbian OS).
If you are going to use Internet on ur cell then Samsung isn't a good choice coz u will face lot difficulty to check-mark or radio select since they use thumb touch.
Smart OS: Google Android, Mac (Iphon) Windows, (Loads n loads of softwares, u can do every thing u would do with a PC).
