Query: Defective cameras

The Canon S400, S410 and S500 have all had serious reliability problems. Read the reviews on this website and you will see that many customers have had a mysterious 'memory error' and/or the lens jamming (E18 error). These problems have shown up at about 18 months on all of these models. Since Canon hasn't fixed the problem in over 3 years since it first started showing up, I wouldn't want to bet that the new SD300 camera won't also turn into a paperweight after 18 months.Oh - I forgot to mention that Canon will 'fix' the cameras for $150. Nothing like turning a defective camera into a profit center.
