I just recently picked up the Canon PowerShot SD750 to replace my PowerShot s410. I like that Canon finally decided to include a variety of preset modes, and I think the pictures are pretty darn good for an ultra-compact, though I wish I could just carry my DSLR all the time.
I like the large LCD screen, which is part of the reason I picked it over one of the IS models (also because it was a little cheaper and a little smaller). I chose a Canon just because all of my other digital cameras have been Canons, and their menu systems are more intuitive and easier to use than many other makers. I still shudder when I think about trying to navigate the menus on my original Olympus.
