Before you buy this, try to look for reviews and user experience (elsewhere). I believe DP1 had a great future that never came. People seem to find it slow and clumsy to handle. Of course it's a fixed lens model, so that focal length's what you'd have to live with. DP2's out I believe but I haven't read much of it yet.
What many people in your position have ended up with is a Panasonic LX3 and most seem fairly happy with it. I'd give a serious consideration to the brand new Olympus E-P1 also if I were you. It's not that much bigger than a P&S camera and yet has exchangable micro four thirds lenses as an option. It's just coming to stores within weeks, but most comments from pre-release users are very positive.
