I've had several off-forum discussions with both current K Owner's and wannabe K owners. It's interesting to listen to the arguments both for and against the new C1. Current K Owner's are unhappy with the lack of RAID (understandable given that's a significant selling point for the "Premiere" line) and the lack of compatibility with their current 1U and 3U systems, and the wannabe's are still looking for a less expensive solution (but they do have interest in the C1, especially amongst DVD owners).
I do not know the thinking behind the system compatibility issue. The obvious is the desire to keep the lines separate, but the underlying reason remains undisclosed. Perhaps it's to not offend current system owner's that spent large amounts of money to acquire what they own, but that's doubtful given the C1 spec's versus premiere line. I think we can see the value differences in the two lines. Perhaps it's just a "technical" thing, required for that platform and upcoming uses, or perhaps it's a simple cost to build factor. Whatever the reason, it has some current owner's passing on this unit (but that's probably okay considering it isn't aimed at them). The RAID issue is easier to speculate about, probably caused by the desire to keep the footprint small, and cost lower. In any case, most on this forum would be surprised at the how well the C1 is being received in the targeted market. It might not be for everyone, but it is selling. There will always be the "I want it all, and I want it for $10" people, but K is still in business for a reason, and it isn't because they price to reach those folks.
