with regards to the warranty, you can call up canon harbourfront. i believe you can only purchase the extended warranty while its still under warranty. someone please correct me if i'm wrong. better hurry and give them a call, 2 weeks is not long.
CCD and CMOS sensors are actually made of millions of light sensitive cells. As anything that is expose to intense light, it actually degrades as it goes. So the bigger the sensors (DSLR) the longer it will last while the compact ones like A75 etc, with only half or lesser in size is reduced dramatically if not exponentially.
