I was beaten today by our own
Engadget and
The New York Times, both of which reviewed a new on-demand TV device called Akimbo. I was going to (and still may) review this device because it has some PVR characteristics.

Containing an 80 GB hard drive, and about the size of a VCR or TiVo, Akimbo is able to download programming over the Internet on demand. You can think of it as a PVR that lets you choose programming beyond that available to you from cable TV and satellite TV services.
The box is currently on sale for $99. The downloading service is $10 a month or a one-time $170 fee. These charges will get you a library of 2,000 TV shows and movies you can download. Unfortunately, not every show is free; some carry charges of $2.99 or so for a month's viewing. After that period, you have to pay up again to watch them.
The review in the New York Times was brutal. Here's a snippet:
"And despite Akimbo's claim to be `the first digital quality
video-on-demand service over the Internet,' the video quality is
erratic. None of it is high-definition, none of it looks as good as a
DVD, and some of it has the blockiness and pixellation of a Web cam.
One children's series is so obviously a transfer from a VHS cassette,
you can actually see the white streaks of the VCR's dirty heads."
