"A long time coming and worth both the wait and the price"4.5 starson by gregpg
Pros: Full featured, versatile, and easy to use
Cons: Built-in program storage is too small, officially supported storage expansion options too limited
Summary: Pay no attention to the negative reviews from ignorant folk who've never used one of these boxes.
I was a happy TiVo series 2 owner for over a year before this unit came out and it was definitely worth the wait. HD recording plus the smart, versatile, easy to use Tivo interface are alone worth the price. My 79-year-old mother, who couldn't program a VCR for a million dollars, uses this TiVo like a pro. We have the unit connected to antenna only and the picture quality generally exceeds the quality our neighbors get with cable DVRs. Being able to record two programs at once from any combination of sources (Dual ATSC or dual NTSC tuners or dual cable cards if installed) is another plus. The icing on the cake is the ability to play photos and music from my computer, as well as movies on demand from Amazon Unbox, on the living room TV by simply pressing a few buttons on the remote.
All that said, there are a few caveats. Room for only 20 hours of HD recording is insufficient, especially with multiple viewers in the house. Without an inconvenient work-around, the unit's ESATA port only works with the TiVo approved and marketed 500 GB "My DVR Upgrade" drives.
