smart phones

I think smart phones are the most important technology in my live. A smart phone is a mobile phone combined cell phone and basic computer functions. I can call, check e-mails and watch movies by using my smart phone. I do not take a laptop with me anytime because I have a smart phone. I also can download useful applications to my smart phone, so I do not need a extra dictionary or notebook. I like smart phones because they contains many functions and they have a small size.
