I hope so. Netflix's interface is better, especially on PCs.
I have a Roku box, and I like that interface. It's easy to read, quick to browse. Of course, the interface I'm using is for a Rokue N1000, which is the 1st Gen Roku boxes, and their update stops at 3.1, while I believe the new interface for Roku 3s and higher is 5.0, so one's mileage may vary depending on what one has.
