I particularly like the part where it suggests changes to pasted code.
When I copy and paste code, very often it needs some small changes (like changing all xs to ys and at the same time widths to heights).
It's very good at this, and does the right thing the vast majority of the time.
It's also good with test code. Test code is supposed to be explicit, and not very abstracted (so someone only mildly familiar with a codebase that's looking at a failing test can at least figure the cause). This means it's full of boilerplate, and a smart code generator can help fill that in.
