Summary: Excellent lens with some issues
Comment: I have owned and used this lens for about 4 months now and I must say I am very pleased with the lens. For starters, this lens would fall in the same category as the 14-54mm lens which was the kit lens for the E-1, I used this to replace my 14-54mm lens on the E-510. Initially I was a little disappointed with the large size and weight of the lens when compared to the 14-54mm, but then it made sense as I was getting an additional 8mm in focal length range as well as ED glass to prevent CA.
The lens is very well built and seems very solid in feel. The zoom action isn't as smooth as the 14-54mm, in fact it feels a little sticky. This will be very noticeable to any long time 14-54mm user, however you tend to get used to it with time.
The lens exhibits noticeable distortion at the wide end, so if you're shooting straight lines (architecture) or trying to fit a big group of people into a frame while shooting in a small room, the lines and faces at the edges will be visibly distorted and although lines can be corrected, faces cannot, so beware!
The lens also exhibits quite a bit of flaring, which was never an issue with the 14-54mm lens, in fact the lens exhibits flare even when shooting indoors with a small light source on the side. This can be very annoying and does spoil a lot of pictures.
Overall though, the lens has an extremely usable focal range which pretty much eliminates the need for any other lens if you're a casual shooter. The AF fast and silent even on the E-510. Contrast and colors are excellent and will never disappoint.
So if you can get over the bulk, mild wide-angle distortion and occasional flaring, this lens is for you!

Summary: Best general zoom in the universe?
Comment: Okay, apologies, a slight exaggeration...
It is simply the best general zoom on this planet! :) Enough to make users of other brands with bigger market share give envious looks across their shoulder to see what the fuss is all about.
Olympus' expertise in optics shines through with this lens and has been commended from all corners from professionals to users to reviewers -- and rightly so. I have had this lens for over 3 months now and it is probably more popular on my E-420 than with the 25mm Pancake! If I don't need extreme portability, then this lens takes priority for good reasons.
Colour capture is stunning, detail is sharp, chromatic aberration is almost non-existent, AF speed is nippy and the 12mm to 60mm (24mm to 120mm) range is extremely useful. My favourite is using it at wide-angle but this lens is consistently great at all ranges. Macro shooting is great as well with nice bokeh at tele' end.
For negatives -- and I am nit-picking here -- there is slight complex distortion at 12mm but nothing that concerns me too much (and I shoot mostly in wide), it is a bit weighty on my E-420 to make it front heavy which might concern some people if they have a smaller body, but I quite like it like this, and, lastly, I cannot shoot with pop-up flash, but I tend to avoid using flash as much as possible as I like having natural light in my photos.
All in all, whether you are a current Olympus user or not, it is definitely recommended for all who are interested in an `all purpose lens', who are passionate about photography and value `it's the glass' philosophy that some people swear by. My photography has certainly come leaps and bounds from using `quality glass' and, in this Zuiko, it has certainly marked a standard that others still have to reach.
Happy lens hunting.
