I played with the demo Premiere at Best Buy last night. I left ambivalent. The Tivo pause/play/rewind features are as awesome as every. I love the 6-second hop-back Tivo has after a fast-forward. (I fear losing that one awesome detail on a 7MC system). And the Premiere's 30-second jump is cool. And going up from the TivoHD's 20 hours of storage to the 45 hours on the Premiere would be really great. A pair of Premieres, with its' 5x faster transfer speed would also be good. And I liked the live video available when navigating the menu.
But the interaction at the menu level, the guide, the HD interface...it felt sluggish, unimproved over TivoHD. It wasn't painfully slow, but it crossed that threshold to where I noticed the brief hesitation with every menu selection. The HD interface isn't finished: one level deep and the old SD menu returns. The guide interface is unchanged from the Tivo HD, and no more responsive. It's a good design, but I had the impression the Premiere had some new awesome way to find, explore, and select TV shows. I never saw it.
And the $200 price jump for the XL, with 150 hrs storage, is steep.
The whole affair felt half-baked. Not lousy, but not impressive.
I'm increasingly interested in a media center system. As a luxury item, I want a single box to watch TV or movies on. As I toggle between Tivo to the Blu-ray to watch some Prison Break on DVD, I am annoyed by devices turning on and off, and waiting (and waiting and waiting) for the Blu-ray to come up, and then swapping discs when I've seen the four episodes, and then a power and input switcharoo to get back to TV.
Still, it is tempting in the short term to upgrade one Tivo: if I could buy a Premiere for $99 and keep my $11/mo sub, it would probably be a good buy. Presumably, I could swap the cable card from the current HD to the new Premiere without a cable-co service call. I should contact Tivo about it pricing.
