Tonight, TiVo announced its new Series 4 DVRs, called Premiere and Premiere XL, which will ship next month. Engadget covered the announcement in New York, so I'll skip the product details. However, one of the most intriguing aspects of the announcement is that the Premiere's user interface is built on Flash, and its performance looked quite smooth. While Apple and Adobe are throwing spitballs at each other over Flash on the iPad, TiVo has just moved Flash front-and-center into the living room. It remains to be seen whether the Premiere will halt TiVo's slide in the DVR business, but at least it indicates that the company isn't giving up on the hardware business.
