Man, people are quick to take things the wrong way. You two (Rocky and Peerke) are imagining things. If I had said "lots of people are happy with their cameras, which is fine by me (and none of my business), but for my purposes, the T1i falls short sometimes" you wouldn't have read into what I wrote. I hope your equipment continues to serve you well for a long time...I can see where you're imagining that I am wishing ill, but that strikes me as more than a little stretch.
I would also like to be able to do everything with just one camera, forever, but feature creep and simple technological advancement means that sometimes the new cameras promise to perform a lot better for me than older models. Low light especially (though for the best low-light performance and other features I'd prefer a 1D(s) Mark IV...obviously, money prevents this).
