Need help finding a digital camera for my husband's Christmas gift. Any ideas?

My husband has a digital camera he carries everywhere with him...but he is very frustrated lately because it is slow and has quite a bit of lag between when he pushes the button and when it actually takes the picture. So he has pictures of our toddler AFTER she has finished the cute moment. I would like to surprise him with a new model, but I'm having a hard time finding one that is fast enough and meets all the requirements he has for a camera:

--small enough to fit in his jeans pocket

--fast (previously mentioned)

--sturdy (again, so it can be in his pocket)

--easy to use (he gets frustrated with technology when it doesn't do what he wants)

--mac compatible

--Comes with a case or has a compatible case that can be purchased

--Decent zoom

--Decent resolution

I am looking to spend about 200 dollars, but for the right camera I would go higher. If anyone knows of a good camera that meets those requirements, would you let me know? Thanks!
