How is this phone useful for the working/traveling person who wants to carry all address/phone/calendar info with him/her all the time, in a small, light and very cool-looking device:1. Synchronizable PDA: If you have an office job, and already keep an online calendar in your company such as Lotus Notes or Outlook, you can synchronize your calendar, and have your phone remind you for everything you have to do, everywhere you have to be. Yes, adding new stuff to the phone directly requires a few more buttons to push, but when you synchronize, it makes life so easy, and you don't have to carry a PDA AND a phone at the same time.2. Taking Pictures: You saw something on the road completely funny, or you have to write down some traffic-jerk's licence#? Just take a picture.3. User-friendly calls: Not much to say here, but the user interface makes it very easy to place calls.4. Games: Although you won't have too much time to play games, especially if you are that veru busy person... it is still a great help on the plane or while waiting for someone.5. Huge screen: Great, bright, colorful screen. Perfect.6. Internet access: You can get your emails, access other websites, etc. Yes, it is not as fast as a computer, but if you need it, it's there.7. Profiles (ring/alert/vibration settings for different environments): You can select and customize settings for meetings, normal times, outdoors, completely silent environments like movies, etc.There's much more to this phone than these that I have counted. Check this phone out before you go out and buy a phone. The only thing you will see is maybe the size of it. While every phone is getting smaller, this is not particularly a small phone. But to have all these in it and also a good, wide screen, and not being heavy at all, it has to be at this size.
