General

compared to recent entry-level DSLRs
"Quite simply, taken as a whole, it is the best camera of its class that we've ever seen, and one of those rare cameras that won't look out of date in a couple of years' time."

Form factor

"Construction isn't bad for the price, but with the EOS 550D it is clear that you're paying for the features, not the build quality."
dpreview.com | talking about the camera's build-quality
"The 550D doesn't provide a flawless handling experience though, and we do have some criticisms. The buttons on the rear are rather flat and close together, which makes it easy to mash them by accident, and very hard to press them accurately if your hands are cold/gloved/large."
