This product is still very very new (barely shipping yet) but is #1 on my list right now. I'm just wondering if the hard drive in this unit (40GB) will be upgradable, similar to the way the tivo units can be upgraded for larger capacity. I'd love to stick a 120GB in this to triple the capacity. The 40GB drive supports about 52 hours of recording in EP (low quality) mode. I'd love to get this same amount of time (or more) in SP mode. As this unit matures and if anyone knows any info about this please post here!
