I only currently have an ixus so the build quality is pretty standard, all metal body. However the lens seems to like dust. Back in 2008 when I got it after about a month a speck of dust appeared on the rear or one of inside elements, making this giant black dot on all my photos. Took it back to john lewis (after 20mins arguing with the assistant that it wasn't my fault) it was sent back to canon. Now its happened again

. Unfortunately just before I plan to get my 60D. Wasn't intending to replace the ixus for a few more years but looks like ill be replacing it after the 60d..... Probably should buy a waterproof one....
Looks like ill be using content aware tool in PS CS5 a bit more now
