Before we go right into a complete comparison, here is a brief overview of how the 30D matches up versus the A55 with regards to portability, imaging, features and an overall rating.

Here is a preview of the gallery photos for Canon EOS 30D and Sony SLT-A55. The complete galleries are available at Canon 30D Gallery and Sony A55 Gallery.

In many cases, it is difficult to visualise the gap between sensor sizing simply by reading through a spec sheet. The photograph below will give you a stronger sense of the sensor dimensions in the 30D and A55.

As you can see, both cameras feature the identical sensor size albeit not the same resolution. You should count on the Sony A55 to give you extra detail as a result of its extra 8MP. Higher resolution will help you crop shots way more aggressively. The older 30D is going to be disadvantaged when it comes to sensor tech.
