Thank you Dailymeel. This was a helpful post.
I am going to be taking two Sony cybershot T's with me this year (along with the three phones...). My big guy is being left at home. EEP! but we are trying to travel with carry-on only. Here's hoping it works.
I love your sketch book idea and now plan to stop off when we get to the US and pick up a book and paints...I'm not as accomplished as you, but I do love to sketch.
