Here's an one click root tool for Android, UniversalAndRoot:
A new and simple root method..."UniversalAndroot" - Android @ MoDaCo

Developed by some Taiwanese developers on the root exploit released on xda. Comments on the blog are generally positive.

It is also opensource (shakalaca's UniversalAndroot at master - GitHub), which is scary. But that's a story for another day.

Just install the APK and follow the instructions: http://bit.ly/aa4jxJ

May take more than one try
