Sony Ericsson W300i Walkman

The Sony Ericsson W300i is the lowest model in the Walkman phone line, but that doesn't mean it is in any way the least capable. The device can play MP3 files and has a built in FM Radio tuner that uses the supplied in-ear headphones as an antenna; which receives surprisingly clear signal. The sound quality of the phone is sub-standard when using as a traditional phone, but when you plug in the supplied in-ear headphones with microphone and you have a rich stereo experience not only when listening to music, but when playing games on the built in JAVA platform, or even while making a call. The built in BlueTooth has more features than you would expect from an entry level media-phone. When connecting to the test laptop (13" Intel MacBook) the phone showed up not only as a phone, but also as a controller and I was able to use the numeric keypad on the phone as an secondary pointing device. I could move the mouse cursor, click and double click using the up-down-left-right and action keys surprisingly naturally - a feature not needed for a phone like the W300i, but a serendipitous addition that I played with way more than thought I would.
The negative aspects of the phone is the lack of the ability to sync to a PC. Even though it will communicate with and mount on a computer as a phone, it will not sync the contacts, calendar or bookmarks. Something that all phones that can communicate with a computer should do is at least sync the contact list with either Outlook on Windows or Address Book on a Mac. It may mean more programming before phones are released, but honestly now! With the line between computer and phone being as blurry as it is, all phones should have some avenue of syncing their contact list with the user's computer.
Over all a very nice Walkman, an adequate phone, a fun pointing device, but an unintelligent Phone-PC interface.
