Careful, the Apple fanboys don't like it when you suggest something else might also be quite good.
My housemate has a HTC Sensation, excellent phone. Brilliant for web browsing and she can't stop playing Angry Birds on it! The bigger screen makes one hell of a difference.
I've always coveted the Samsung Galaxy Nexux and Sony Experia Arc S myself. The Motorola Razr is also very impressive. If you don't want anything tablet size then stay away from the Samsung Galaxy Note, stunning bit of kit but it is almost the size of a small tablet with it's 5.3 inch screen.
Try this website for a few ideas, there is an awful lot out there though. You should be able to get something for half the price that can effectively tick all the boxes.

(Before anyone says, I am an iPhone 4 owner, I love my phone but have begun to feel the itch to see what else is out there.)
