What is the best Smartphone?

What is the best smartphone? I am probably one of the only people, if not the only one, in NYC who doesn't own a smartphone. Still, when conformity finally sinks in I want to ensure I make the best decision. To wit, what is the best smartphone?

Is it any of these major players?

• iPhone (do I even need to say 3G?)
• BlackBerry Storm (or, perhaps, the Pearl, Curve or Bold?)
• Treo (yes, they are still around!)
• HTC G1 (AKA, the Google phone)
• Nokia E71
• AT&T Tilt
• Samsung Omnia

What is the best smartphone?
Did I miss any?
Should I even bother with a smartphone?

What do you think?
