Never, ever, ever purchase a piece of technology prior to its release. There are always bugs, sometimes major. Why be the Guinea pig that gets to test the product? My rule is never purchase any technology until at least 6 months after it first hits the market. Plus, if you wait a bit longer you will pay less--often a lot less. The first adopters pay through the nose to be beta testers and often end disappointed. How many times have you read about some product that sounded great in the PR material and then turned out to be a disappointment?
