Im going to say take a hard look at the Panasonic G1.
It has a four thirds sensor system which gives it the quality of an DSLR camera, but without the size. (It replaces the reflective mirror in the DSLR's with an electonic viewfinder).This means its also really compact too.
So you have a compact camera with DSLR quality.It also has a really high def pull out/twist LCD on the back, plus a electronic viewfinder that can give you previews of the scene modes etc. Something a DSLR cannot do.
Go check out the review on dpreview.com. It comes highly rated. It may have less lenses available for it than the traditional crowd, but the lenses that are available are high quality.
I am currently considering this camera as DSLR's are too bulky, and compacts suffer from far too much shutter lag.
Here is a pro/con list from someone who reviewed it on amazon :
This camera is well suitable for:
1) Enthusiasts currently using bridge/compacts who are looking to upgrade to a camera with better fexibility, resolution and image quality.
2) DSLR users who find having a full DSLR kit (lenses and camera) too bulky and heavy to go around, but do not want to compromise on quality.
3) Entry-level DSLR users who have few lenses and can easily afford to swap over to the M4/3 format.
4) Travellers (I am one).
5) People looking at DSLR alternatives and would not care to buy 1000 quid lenses, but rather stick with VERY GOOD kit lenses that would cover the range of everyday needs.
This is definitely not for:
1) Professional DSLR users or pixel-peepers with a huge selection of top-class(expensive) lenses.
2) Stubborn people who cannot accept a modern format but rather, stick with a 60-year old technology. DSLR snobs, in short.
3) People who regularly prints at >A3 sizes.
4) People with gorilla-sized hands.
5) people who also want to use their camera for Video as well as photos (no video mode).
