TIVO promised the Roamio OTA on Sep 14th. Best Buy says they have no idea when it will be available. TIVO says the same thing. Why is it not available for preorder on TIVO or Best Buy web sites? It makes it almost impossible to buy one of these, and yes, $15 a month for "service" is ridiculous - one can use station schedules on the web.
Making a promise is one thing. Keeping a promise is completely different. Just ask any politician. Additionally, ithout a firm release date there's no point in making the product available for pre-order.
