This is and always would be the big question - and I dont quite understand why we havent seen many posts on it. How good or even how much better is the LX than the XD with SD? It is a given (particularly for the price difference) that for HD the LX will be if not as good then perhaps better than the XD. Individuals could make their mind up whether the difference in quality is worth the difference in price. However the big question for many who already own the XD or are wondering about which to buy is how much better (if at all) the LX is over the XD for SD - which is what most will be watching for the forseeable future. Many like me were persuaded prior to the release of the LX that it was likely to be the same or more likely much worse for SD. Now the LX is released it appears this may not be the case. I dont understand why there are so few comments on this. I have seen the few comments there are on the 8G owners thread and the LX owners thread - but these are informal and brief. I know ******** has both and has indicated he will compare - but until then there is precious little. I dont understand this -because this must be the most important differentiating issue for most current prospective purchasers.
