Thanks for the comments. The DOF in the first shot one of the things I'd been looking for when I decided I wanted this lens. It's rare that I get a completely clean background, but with this lens, I can really minimize the distraction a cluttered background provides. Add in its capability for indoor and lowlight action shots and it seemed like the perfect choice.
His oldest brother used to call the remote the "thank you" because everytime he picked it up, we'd put out our hand, he'd hand it over, and we'd tell him thank you.
Our middle son was given a old remote with its batteries removed by my parents. He thought it was great for about a day. Then he realized that no matter what buttons he pushed, nothing happened. It wasn't nearly as appealing after that. 
This one is equally attracted to everything electronic -- telephones are also a huge draw. He has no idea what they do, but he sees everyone else in his family with them and doesn't want to be left out.
