I wonder, did you get a special agreement with your SPro2 purchase that the rest of us didn't get? Did your purchase price include an exclusive contract stating that MS will notify you when any hardware changes were eminent or that you are entitled to all future hardware upgrades?
Customer loyalty doesn't mean that you get upset because hardware upgrades were made a few months after you purchased your device. Customer loyalty means that you value your device and rejoice when they upgrade hardware. I'm excited for those of you who have received a bump in your hardware. I'm excited for those of you who, unlike me, waited a little longer to purchase your device. Me? I wanted the SPro2 on day 1. I'm happy with my purchase. If I truly want the extra bump in hardware, I can sell my SPro2, eat the cost, and turn around and buy a new one. In no way do I feel entitled to a free upgrade.
Well, there's just a psychical reason...
I mean you just cannot prevent yourself from thinking: "Damn, why do all those who buy now get something better for the same price as I did? :c"
It also really isn't a good thing for MS because it tells for the future products not to buy at the beginning but to buy later because they might improve something at the device.
Personally I'm pretty sure that I'll never really require the power the i5-4200 provides but it still just bugs, lol.
If they'd also have upgraded the cams on the device with this occasion, I'd probably do what you described and rebuy it...
Fact is, 2 months are just too early for an update. It's doubtworthy whether that's the right way to go, but I'd almost say they should have done what someone up there said and downclock the new devices to keep it fair and not to turn down people who already bought it...
On the other hand MS probably profits now because all media says "The SP 2 got even better, so buy it!", lol. Oh well.. the customers are always the losers xD
