I recommend the C65.
I used to own an X60 (same sw as the A60), and it was indeed slow. I don't know the i62, but open Android is more than worth the 10$ price difference. For example, you can install a fast web browser (such as Opera Mini) which is likely to be maintained and improved over time. This is not always the case with the proprietary apps of device manufacturers, who would prefer to sell you a new device.
