P168 runs on Symbian which is a type of OS called linux used for mobile phones like Sony Ericson, Nokia etc. It is open source that's why the OS is free and phone is cheap unlike Windows or MAC. It is designed totally diffrent, you can download software (called packages) using the command line. The problem with most useres is that they have no clue about linux and it's capabilityies and it's proper usage.

...and no you can't use Mac or Windows on that phone.

Linux rules again! Windows Sucks...
