The goofy Samsung Galaxy Camera--a point-and-shoot with a 4.8-inch touchscreen and a full version of Android--came out of nowhere and actually impressed us. The interface is fast and efficient for changing settings, the screen is great, and the camera has some pretty decent optics to book (21x optical zoom lens, 16MP CMOS sensor). And we just got an email from AT&T telling us the camera will cost $499.99, either with or without a 4G data plan. Yoooouch. That's even more than the $450 Canon S110, the reigning champ of advanced compacts. We'll have a full review soon so you can see if it's worth it.
