When I first started seriously shopping last August, the salesperson told me that it was just a free software upgrade, and would be available within 90 days.
That just about came true, but of course it was far more than that, with the necessary USB hub upgrades and the added costs.
When I finally pulled the trigger in December, I negotiated the $399 quoted install cost to be included, and I got it in writing as part of the deal... and thankfully, when they installed in a week and a half ago, they honored the deal.
So much of the early speculation around AA/CP was based on half-statements and rumors at best, and spread like wildfire on the Internet. The salespeople, early on, didn't really seem to know anything, but when one sales guy said something and then the customer posted on the internet, it was all accepted as truth. An unfortunate symptom of Internet culture.
The key, I've found in any sales negotiation, is to get everything in writing. Anything someone tells you during the process, but not included in a final contract/agreement, has absolutely no bearing when it's all said, done and paid for.
