don't get your panties in a bunch youngster, I have been in photography for 8 years, maybe that makes me jaded in my view of the m43 system. making personal attacks on who I talk to is not a way to go. As for my discussion of the APS-C sensor I think I cleared that up and addressed it by post # 21 and have not mentioned it since. Further more here is what DpReview had to say.
DpReview:
As the heart of an extensive interchangeable lens kit the GF1 has a hard time competing with a true SLR or, for that matter, the G1 or (if you want video and have deep pockets) the GH1. It makes little sense when used with long zooms, and the superb viewfinder and flip out screen sported by its siblings make them considerably more versatile shooting tools. But as a second camera - be it as part of an existing Four Thirds/Micro Four Thirds system or as a compliment to a larger APS-C kit - it is incredibly easy to recommend - especially with the 20mm lens.
Crucially, although you get the best results from the GF1 by shooting raw (and you'll need to fiddle with a few parameters to get the most appealing JPEGs), it's a lot, lot easier for novice users to get good pictures out of it than the E-P1. The iAuto mode rarely gets much wrong, with very reliable metering and fast, accurate focus, and its perfectly possible to just point and shoot, if that's all you want from a camera. It might only look like a few milliseconds, but the difference between the autofocus on the GF1 and the Olympus E-P1 feels like night and day when you're trying to get a shot; it's the difference between a transparent user experience and a frustrating one.

DpReview:
The GF1's performance was always going to be judged by two measures; the typical mid-range SLRs it competes with on price and the Olympus E-P1, its only direct competitor. And whilst it can't quite keep up with most modern SLRs, it's really not far off (and is sufficiently close for most typical users of this kind of camera). Compared to the E-P1, however, the GF1 feels fast and responsive, particularly when it comes to focus speed, the E-P1's well-documented Achilles Heel.
Unsurprisingly the performance is very similar to the G1, which is no bad thing; not quite as fast as an SLR, but a lot faster than 99% of them when used in live view mode... and a lot snappier than pretty much every compact camera on the market.
