Query: Best Gadget Ever!

It is so great to not have to tied to the schedule set by the networks. Furthermore, an hour long TV program can be watched in about 45 minutes when you skip through the commercials. The only drawback to the unit is the lack of a fan. I found that it gets extremely hot when in my stereo cabinet, even with a few inches of space on all sides and top. By keeping it on top of the cabinet it runs MUCH cooler. The only problem with this is you can hear the whine of the hard disk. Thankfully, it is not so loud as to be more than a minor annoyance. I don't ever plan to be without a DVR again!
