Canon is not Sony.
Thank God Canon is not Sony!
Sony drops their products without any consideration or support for their customers who bought them ... remember Plasma TV? alpha 900?
I spent good money on a Plasma TV back in late 2005 and in less then 18 months they dumped the entire product line and came up with a tag line "we stand for LCD" ... the worst part was that they refused to provide support for my Sony Plasma TV. With that kind of attitude towards customers, it is little wonder they posted 7th straight quarterly loss (as of Nov 2012) and 4 consecutive annual losses.
