My current Nokia handset is really old which I bought Oct of 2005 to replace my elder Erricson which I have used 3 years in the colledge. After two years companision, the Nokia is wore out. Paint began to peel off so much that all charactors on the button couldn't be seen. 

It's time to replace and my budget is 2,000 rmb. So what kind of mobile phone do I need with this limited budget? 
*It should be looked professional and cool. 
*It should allow me to jam many books in. 
*It can play music for me. 
*It should be cabable to accomadate as many as contact lists *It has enjoyful game 
*Other functions like GPRS, infrared community, bluetooth capability is the more the better 
All in a word, it should be a powerful business phone. 

So what is that? 
That is a smartphone. What is smartphone? It reads this on wikipedia: A smartphone is a full-featured mobile phone with personal computer like functionality. Most smartphones are cellphones that support full featured email capabilities with the functionality of a complete personal organizer...blah and blah.

It really hard to choose a smartphone because smartphone is a collection of many kind of smartphones classed by operation system. At least there are four operation system, e.g. WindowsMobile, Syibian, Palm and Linux. The one I most likely to buy now is a Palm smartphone, Treo 650 Blacktie Edition. It's very cool and fowrful. The most important is that the performance price ritio is very attractive. Have a look at it here and give me your comments.
