30d vs 40d

Little T

Ok i know quite a few of you out there have probably used both over the years and i could get some honest feed back here.

What exactly are the differences between the 30 and 40d?

30D is a mildly updated 20D with no resolution bump.
40D was a major step in resolution and features.

from dpreview:

Eighteen months after the EOS 20D comes the EOS 30D, which honestly has to be one of the least exciting upgrades so far. The real headline improvements are a larger LCD monitor ..., spot metering, third stop ISO selection and selectable continuous shooting speeds....Canon has taken the "if it ain't broken don't fix it" approach to the image pipeline, the EOS 30D has the same sensor and image processor (DIGIC II) as the EOS 20D, and that camera has for the eight megapixel digital SLR benchmark since it was introduced.

Here is a link to the dpreview. It outlines the improvements.

The biggest factor you may notice is that the 40D has a slightly higher fps, a bigger LCD, an anti dust feature for the sensor, and a slightly improved viewfinder and Auto focus.
