I really think the X10 lens may be a nice surprise. Looks like Fuji went all out on it which is good because lens matters. But to use the X10 best on that end (the DR) you probably need to get used to the idea of 6 MP shots. As a test I printed in 13x13 inch an LX5 portrait shot I made at ISO 800 and I was surprised how well it came out. A Sigma I know looks superb (dp1/dp2), but that's because the Foveon has richer data per pixel, though you may still get jaggies on some subjects. Also Epson's driver rocks
So given that, I could easily see 8x10 prints out of 6 MP with a high quality lens and DR. And ditto for the web. Now, if you do cropping, then yeah, better learn to frame better (I need to watch a bit there lately). But good prints at 8x10 I think are pretty good, and on a push you could still get 12 MP shots out of the X10 in many situations that still have all you need.
