While I covet a better camera than my T2i, I still have a ton to learn. Maybe it is just me, but I would rather have better glass and a cheaper body, than a great body with junk glass.
It depends on how much one can afford to pay for the equipment. While glass does make a world of difference in image quailty, the term 'junk glass' doesn't necessarily equate with cheap. You can purchase 20-year-old Nikkor AI or AI-s primes that are inexpensive but hold their own against Canon L lens and the Canon's only real advantage may be the lower f/stop and you'll pay through the nose for those. I do all my photography with these Nikkor primes and video with a Canon L zoom lens.
This is why I simply do not understand the whole childish Nikon vs Canon rivalry. If you can purchase a Nikon prime lens that is superior to a Canon one for the same price range and you're a Canon user, who cares. My good friend who's a professional photographer uses a Nikon D3s always helps me out whever I need technical advice on using my Canon and photography tips.
In the future you may want to upgrade to a 7D or even a 5D. The lack of buttons and a dial on the back side of Rebel series makes navigating the cameras menu system a bit slow and clumsy. The transition from photography to video is as simple as pushing the live view button on the 7D or 5D while staying in manual, but with the Rebel you have to switch the dial from M to the video icon. Again, that's the disadvantage of a cheaper body.
If you do a lot of video, you'd notice quite a difference going from a cropped sensor to a full frame one (5D). With a cropped sensor you may have to pull back to achieve the same area of coverage a full frame sensor is able to, however when you do that you may be giving up depth of field. With a full framed sensor, you have a bit more latitude in post editing, you're able to crop the video if need be, if you're already working with a cropped video then your options are limited.
