1 and it's all I need and want to manage. I hate laptops anyway. My desktop is my gaming and primary pc. I can also use FIOS media manager to share out to the various tvs in the house. It's easy and free, though the quality is not the best. Otherwise I netflix through ipad / smartphone.
BTW, I need to point back to this thread the next time someone argues "do you really need a nice purse, fast car, etc.". Look at all the extras when it comes to tech toys.
