What if i bought the Tivo today at Bestbuy, for $300. And try to activate it tomorrow, when the price is down to 100. Are they going to demand proof pf purchase, or just refuse to honor the old subscription plan? I really hope Tivo is not stupid enough to try and pull this crap. They're just trying to trick new buyers into paying more, since $20/mo is a lot more revenue than an upfront cost.
