I had planned to wait and get reports from my friends before I went and purchased one, but my Macbook Pro was in for a repair and when I picked it up on Friday, I made an impulse buy. They place the things right near the registers like a candy aisle, so who am I to resist?
Apart from the new need for an HDMI/Toslink switch, without which I need to continually move cables around, I'm very happy with the purchase.
