I exchanged my Canon D30 to 20D at 2005-03-15. The change was done because of following reasons: better autofocus, better ergonomics and better high ISO performance. Below is my little comparison between D30 and 20D based on actual usage not reading other reviews.

20D pros:

• Autofocus is much faster and more accurate.
• Ergonomics are much better, for example focus point selecting joystick is very good.
• Build quality is better, camera feels much better on hand.
• High ISO performance is much better.
• 8Mpix is more than 3Mpix, but at my use when only publishing photos to internet and printing always A4 size, this isn't very big benefit. Naturally slight cropping can be done and still print at A4.
• Better battery life using same BP-511 batteries.

20D cons:

• File size is much larger, before my 1GB MicroDrive was enough for half day travelling in nature but now it's full in couple hours.
• Setting ISO value is much more difficult than in D30 [in D30 you can set the button inside back command dial to activate ISO adjustment, in 20D you have to press one of the buttons in front of the top LCD-screen and I haven't yet learned (= I will not learn never) to find that button without moving my eye from viewfinder]
