If the Bold is too big for your delicate little hands, may I suggest the Curve? It's available now, is an awesome device, and is considerably smaller than the Bold.
Those who ask about comparison to the iphone - more, cheaper apps available for the iphone and the large touch screen makes browsing a little easier.....but the iphone lacks so much that the bold doesn't. Bold ftw!
In terms of size....the bold was the first BB i owned. When i took it out of the box I was a bit miffed at the chunky size of it - but it took about 3 hours to become totally fine with it. I picked up my old phone the other day, a standard mobile phone. It felt tiny and flimsy and I wanted to throw it away.
