The more stuff you buy from Sony, the more you hate them. They make good products, but everything they sell has proprietary bits that make them annoyingly expensive to own after the initial sale. Pro Duo memory that costs several times as much as equivalent SD family, cables with odd connectors, oddball batteries, etc. They may be hitting the tipping point of (new fools coming in) < (fooled me enough times, TYVM).
I just bought an Olympus digital voice recorder. The Sony was nicer for the same price, but didn't include the cable to DL the data, and Office Depot didn't carry it. No sale. The Olympus uses the same standard USB connector as my remote controls, portable HD, cell phone, etc.
