Hah, I thought that sounded a little strange. It's like using an expensive top-of-the-range audio equipment to listen to 64kbps MP3s.
12-15 Lbs? That's like 5000 to 7000 grams (5-7 KGs). That's heavier than an Xbox 360/PS3. A seller emailed me back saying it's about 2000 grams (about 4.5 Lbs) which sounds more realistic.
