Speed and range are two of the biggest improvements. However, BT 2.0 on the Mogul doesn't help me where I was hoping it would... in the Internet Sharing tethering department. 500Kbps seems to be about the MAX download speed using BT PAN, which is a far cry from what the specification can supposedly handle... I was bummed out when I found out wireless tethering wasn't much faster on the Titan than the Apache..
