I have big hands with arthritis, so the thinness of the 350 makes it a little difficult for me to hold comfortably. So I'm actually looking forward to getting a cover to make it a bit thicker. I'm going to make one more pass through my local Best Buys and if they don't have them I'm just going to order one directly from Sony. I would probably get it as soon or sooner than waiting on Best Buy to stock them. I wish I had a Sony Style store nearby, but they only have one in my metro of 6.5 million people and it is 30 miles away through horrible traffic.
