iPod Touch 32GB vs. iPhone 3gs vs. iPad Thoughts

I have often pondered which of these devices is the best to own and use. Currently, I am a proud owner of the ipod touch 3g 32gb, and i was a previous owner of the ipod touch 1g. Boy, does that bring back memories... Anyway, I have been pondering whether or not to use the iPhone 3gs or the iPad. If the iPhone 3gs is released for verizon, this is what I was leaning towards buying. However, the ipad is pretty cool, and the second generation is bound to be awesome. What do you guys think? Is the ipod touch, iphone, or ipad the coolest device? Leave your comments below.
