Tivo offers lifetime subscriptions again - temporarily

My sister, knowing my devotion to all things Tivo, sent me this link to this Engadget blog post:

Call it a quick holiday cash-in targeted at current TiVo owners if you must, but you're not about to kill our buzz about the fact that TiVo's resurrecting the greatly missed Product Lifetime Service (aka lifetime subscription) for Series3 and HD owners -- temporarily, anyway, and for realsies this time. As of today -- but only through January 2nd, 2008 -- current TiVo owners can upgrade their Series2 to a Series3 or HD with lifetime, or simply upgrade the service on their current S3 / HD -- equipment aside, the service will set you back $399.

Tempting, but for some reason I'm just really slow to jump on the HD bandwagon. I think it's the lack of funds to pay for things like HD-ready Tivos and digital HDTV service. (We currently pay $15 a month for basic cable service - HD channels would be many times that.) HD will probably come to my house in the form of a cheap hi-def DVD player first (the jury's still out on HD-DVD vs Blu-Ray in my book), or maybe an Apple TV if they decide to start offering high definition movies for rent. Until then, we'll watch the same old regular definition shows that have been serving man since TV began.
