The Samsung Infuse 4G is all kinds of lovely to hold and sits happily in the palm, despite its 4.5-inch display and thanks to the slightly textured back. Did we mention it's thin? When it launches on AT&T it'll be the thinnest smartphone in the inventory. Heck, it's profile makes our iPhone look downright husky -- of course, with that size, the trade-off we'll be interested to see is how the battery performs. Unfortunately, Samsung wouldn't let us fire it up for a look under the hood but with CES just barely started, we've plenty of time to work our way into their hearts for a real tour. Have a peek below.
