To iPhone 4S Or To Not iPhone 4S

My husband and I upgraded our respective phones over a year ago when the new iPhone 4 came out.  He said goodbye to his Droid and I reluctantly let go of my Blackberry.   And then I fell instantly in love.  And I'm still in love.  I will hang on to my iPhone 4 until Apple releases the iPhone 5, which I think will come within the next year.  (IMO)  However, my husband...

He wants the new iPhone 4S.  So, I ask, is it THAT cool?  Should I bite the bullet and get the new 4S or wait it out?

I'm still not sure.  My husband has played with the new 4S, but I have not.  I think if I were to go to an Apple store and actually hold one in my hand, I would be sold.

But for now, I will wait it out.  As long as I can...
