Get the EX1 if you want the swivel screen, the S95 if you want compact size and don't care about the lack of grip, the LX5 if you're into the kind of look and feel (very layman look and feel factor).
Each has its advantages, I would say. I'm using the LX5 btw and the one feature that I really think stands out is the high speed sync with on board flash, which S95 and EX1 can't offer.
I beg to differ on the comment of the price of entry level DSLR, with LX5 price at around $680 thereabouts at dealer pricing as the most ex comparing between the 3, any other comparison (24-90mm thereabouts with F2.0 or less) should be solely comparing on the aperture and range. There is a bridge still between the entry level DSLR market and the premium compact cameras mainly because of the specs.
Look at it frankly, is there any entry level DSLR at just a $100 top up (I'm using LX5 as a comparison) that offers the same aperture and focal length, high speed sync, Leica lens etc? Try adding a F2.8 constant lens (if there is for the DSLR brand you're looking at) and the price of the entry level DSLR becomes not so entry level =)
