gorcorps: I agree, the Roku is not for everyone. It works well for what I need it for, keep my kids media stored and shared in a remote location while giving them access via the Roku + Plex. My sons would wreck a HTPC because that's the nature of boys...can't keep their hands of stuff, want to take everything apart to see how it works, etc..
The Roku has a small footprint physically and electrically, has an easy to use interface, and I can limit what my kids can access for the most part. Netflix takes some monitoring, but I'm monitoring it either way sine my kids are still young
It lacks support for DLNA, which is a huge negative. Plex can be a PITB sometimes, but works for the most part.
I guess my point is, if it's not what you want then don't keep it.
