I've viewed K-scope from afar (because I can't afford it
). Even at 8K, that's expensive. However, I love the concept - as I've turned my HTPC into my main prepro. I still put the disc into my BD drive on my machine and play BD's, I've ripped my music to my NAS and I'm very satisfied.
What I see with the K-scope is that I still have to rely on someone else to fix something when it gets broken. As a computer tech, I fix my own gear and I make sure I have backups (because eventually - all HDD's fail). I like the ideal of everything being at the K-Store for instant retrieval - that would be a big selling point to many - but not 8k worth for me. For a person that tinkers - it may be a pain to re-rip, but you'd do it if you had to.
For people that have that type of cash, I see the K-scope as a pleasant, turnkey device that will bring simplicity and convenience to their entertainment experience, nothing wrong with it at all. However for those who have the DIY bug, and are techies at heart....you'd just do it yourself ... even if you had the cash.
