I had this Blackberry phone in Sunset (red) for many years and feel it is the best phone I have ever used for work. First off, I like that it includes an entire keyboard (what blackberry does best)! This makes it easy to type long emails and edit documents. The track ball is also awesome and makes it very easy to scroll through messages, emails, etc. The phone also looks attractive and I enjoyed being the sunset color. Also, I really like that everytime you have a message or email the red lights flashes on the front. This is convenient because it meetings you may not want your phone to go off but you can always look for the red light. This phone also has built in features that are great for work. The calender function is really great and displays events on your front page every day. I really enjoy that type of reminder and I have not found another phone with the same function, usually you have to go to a different screen for event reminders. With the Blackberry the reminds are always right there when you open your phone. I also like that you can read the beginning multiple messages and emails on the front display screen before actually opening the phone. I also found the durability, battery life, call quality, and design to all be great. That being said, this phone does not have that many apps and does not have a great camera which is why I strictly used it for work.
