Some sites seem to get a bit over excited by seeing a retailer issuing pre-order status on their online sites. What’s the point? It still means basically not in stock and likely not anywhere near being in stock and most certainly not even with a remotely realistic date of release. I’m sure some sites just put things on “Pre-Order” status just because they know it will get them some decent web coverage from over-excitable fanboy sites. Pre-Ordering generally doesn’t get you the device any earlier nor it does tend to get you any additional benefits.
Personally I’m not interested in putting down any indication of purchasing a device until it’s either in stock, in which case I know the price and availability, or at the very worst, listed as being available on a set date from a very reputable dealer.
