If you're in the market for a smartphone that isn't an iPhone, and you don't think that you're ever going to want to listen to music on said phone, the Veer 4G ($100) might be worth a look. However, due to the poor experience with the headphone jack, and high price (compared to the iPhone 3GS), I really can't recommend this phone.
According to HP, the small size of the Veer shouldn't translate to a lack of functionality. The phone has a 2.6-inch 320x400 multitouch display, an 800Mhz CPU, 512Mb of RAM, and 8GB of flash storage. But it's the size of the Veer that is easily its most impressive feature. It's hard to describe how small it is — you just have to hold it in your hand to see. It's so small that I was frequently worrying about losing it. I don't think it's possible to make a phone much smaller (maybe you could do this size, but thinner). I did like carrying it around, and as I have shifted more of my non-Mac time to the iPad, I could see having a smaller, less powerful phone that is something of a "tablet companion." That being said, I think that for all-around use, the 3.5-inch display in the iPhone is probably the sweet spot, in terms of still being pocketable, yet providing a good size for use. Yet there might be a killer product in the space — I could see how people might prefer a smaller phone, like the Veer.
