Yeah, big time. The transfer rate from Tivo to PC is about the same speed for the S2 and S3 models over ethernet (I've got both). Neither Tivo can output data faster than ~10Mbit/s, IME. I think the average is about 7Mbit/s. Obviously, HD shows on from the TivoHD take way longer than SD shows recorded at basic quality on my S2, but that's just because of the file size. The bandwidth is about the same.
OTOH, people have reported that a Premiere can transfer to another Premiere or a PC at around 70Mbit/s. 10x faster. It's all due to the faster processor in the Premiere. That alone is tempting me to get one (probably replace my S2).
