After using my sp3 very carefully for 3 or 4 months, i've had to send it back to get a replacement. one day to the next it just wouldnt start anymore, no response to pressing the power button. Thing is, i've been realy REALY careful with it. Not a scratch, not a dimp, nothing. It could be sold as new and noone would notice. Now that i'm getting a refurb back, i'm afraid it won't be in the same mint condition as the one i sent back. Any experiences with that? Microsoft assured me i dont have to be worried about it but in my experience they have a history of dissapointing when it comes to their repair service.
