Just wondering, and a question directed to business users specifically is:

How useful do you find the iPhone as a business tool? Do you think it's functions are sufficient to keep you productive?

I am concerned because of the lack of many productivity features:
- copy and paste
- sending files over bluetooth
- no task-syncing
- no file structure and inability to view word and pdf files without e-mailing them to yourself

So what do you guys think? how have you been able to compromise? If I'm looking for more of a business/productivity tool, would the HTC Touch be a better alternative? Are there other smartphone alternatives I should look at as well? (that aren't huge and bulky)
