根据以下材料，回答题
If you don′t think a phone is the rightgift for a lover, the smart choice this year is a smart phone.
For people who don′t read instructions
The easiest-to-use phone is the iPhone. It′sthat has pushed it to the No.1 selling position, surpassing the Motorola Razr.The iPhone′s touch screen is easy to operate and it′s also easy to customize (用户化). The iPhone can run allsorts of applications such as those help you to lose weight, identify a song onthe radio, find a restaurant or do many other things.
For the futurist

The system shouldimprove as it becomes more popular, so it holds great promise. With fewrestrictions on the design of applications for the phone,
the G1 could be the first phone toincorporate (整合) some of the coolest.
For the road warrior

It stillincorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people.
