I use my Sony PS3 game console for playing video games; my 32″ LCD TV + DVD Player or media player for watching movies and TV series; my personal computer and/or mac for personal computing like spreadsheets, word processing, media-editing, browsing flash-heavy websites, etc.; my Canon 30D DSLR for photography; and my smartphone/s for mobile computing, communications (e.g., calling, SMS and email, IM), on-the-go social networking, and some light internet browsing.
That being said, I don’t use my smartphone primarily as (or as an eligible alternative for a great) game console, movie player, personal computer, or camera. Furthermore, if all you do is texting and calling for a phone, you don’t need a shiny new smartphone.
