I'm having an issue

With my blackberry, ever since starting my new job it's been a real issue because I get my work e-mail on it now. I don't like how if I delete or file an e-mail on my desktop it doesn't delete or file the message on my BB. My contract is up in July and I want to stay with my provider, I get good reception everywhere but I can't keep spending 30 mins a day organizing my BB. I don't know what new phone I want. I just know I want a keyboard not a touchscreen. Any suggestions.
