I've noticed no real compatibility problems so far, and I just upgraded my Leopard machine. (Still took an hour, and I didn't even opt to install Xcode 3.2 yet.) A somewhat odd and annoying change is that /usr/bin no longer contains a number of common tools that are technically developer tools. For instance, there is no /usr/bin/make or /usr/bin/xcodebuild; one must instead look in /Developer/usr/bin. Both Python 2.5.4 and 2.6.1 are in /usr/bin, and it's handy to have both.
