Samsung's curvaceous HMX-U20 was on display at PMA , but unfortunately one of its key selling points -- the optical 3x zoom -- was not working on the floor model.The picture itself was hard to see from the small LCD, so for now we're just gonna comment on the shape, which though unique and purported to be more ergonomic, to us seems like it'd be a pain in the pockets (of course, they didn't let us pocket it to find out, but we digress...). Also at the show were the waterproof AQ100 and scratch-resistant SL605, but unlike Sony's frosty setup , these weren't touchable. Don't let that stop you from enjoying the pictures below -- and don't forget our earlier hands-on impressions of the TL350 and TL500
