You'll think I'm crazy, but I'm watching blu-ray on a 27" monitor
It's an internal SATA drive, I'm sitting pretty close so I'm seeing the detail.
By monitor you mean a computer monitor? Basically I'm assuming it's not a tube tv that has a 640 interlaced display? And yes, sitting close to it and it having a good native resolution makes up for it. Average homes that the seating is 8 to 10 feet from their TV, it will matter.
