I've been loving the Sony Ericsson X10 Mini ever since I caught sight of it at Mobile World Congress back in February. It's all about the size. The Mini really is small -- it's basically the same height and width as a credit card, and about 1.5cm thick. And it's a full featured Android phone with a 5 megapixel camera along with 3G HSPA. Genius. It's not for everyone, but if you've been hunting for a small handset, definitely, definitely take a look.
