I4U has a side by side comparison of Sony's 2 newest slim digital cameras, the DSC-T1 and the DSC-T11. The features, functions and interface are the same. The only difference is the case. The T11 is pearly white and thinner than the silver T1. It's thinner because the sliding lens cover has been removed. As far as I'm concerned, the lens cover is extremely valuable. I keep my T1 in my pocket all the time and the lens cover keeps pocket lint from making its way into my photos.
