The problem from my perspective is that (and somebody correct me if I'm wrong) you can only legitimately buy a WOZ by pre-ordering years in advance. There doesn't appear to be any stock of brand new WOZ machines sold by authorized destributors. So, if you want to buy a WOZ and actually GET IT simultaniously, you have to give up your warranty rights. This puts Jersey Jack in a substantially different position than a company like Rolex, or Pioneer, where you are able to get a product pretty much immediately upon payment (or within a reasonable time after you pay).
In other words, by refusing to honor warranties due to a sale by the original owner to a 3rd party, Jersey Jack is basically preventing buyers who aren't willing to preorder from safely buying games on the secondary market. The ultimate message being sent is, "you better pre-order otherwise your warranty is questionable." As a potential purchaser, it's a little annoying because, if I want to buy a WOZ with a warranty, I have to wait for some indefinate period of time and I'm not comforatable with that business model. If I send $8000 to Jersey Jack, I have no true guaranty I'll get my money back if the company goes under. So, it's either, risk my funds by sending them to Jersey Jack and wait for an indefinate period so that I get a warranty, or, I buy one on the secondary market, get my game immediately, but risk having no warranty at all. I don't really like either of those options.
It seems to me that, because WOZ is not available to purchase on the primary market under normal terms (i.e. you get the product shortly after ordering) the reasonable thing to do would be to honor warranties for the first year regardless of transfer of ownership, so long as the transfer of ownership is registered with Jersey Jack. Or, in the alternative, make sure that there is stock available for the general public to buy. This whole "preoder" thing just causes a mess for so many reasons. Hopefully we'll see a move away from that model.
