600d owner
I chose this particular camera over others due to the strength of the software support...Canon EOS utilility and Magic Lantern
I heard about magic lantern through the film making forums and later on youtube where there are several great tutorials.
I have a very very low opinion of DSLR cameras, they are clunky dinosaurs and consumers deserve much better from the big brand names. Someone at Canon has got half a brain and the hardware & software features of the 600d just about scrape a minimum pass. Thanks to all the Magic Lantern developers, version 2.3 while mildly buggy has helped plug some of the gaps that Canon & others should have plugged 10 years ago !
I also have a very low opinion of open source projects in general, too many cooks spoil the broth and lack of enduser focus, software like magic lantern helps restore my faith in humanity....and my end user sanity !
Well done ML dev team and the end users providing essential feedback and testing.
Open Source software i use with some confidence = Magic Lantern, Audacity (Audio) , Desire (astronomy), FreeBasic ( prog lang )
