Congratulation Jon, refund is definitely better than replacement. Also it's good precedence for those who've been so unfortunate to buy a defective product.

As to the discontinuity of N900, Let's not worry about it. They're just starting to open the sales channels in Asia region for N900. May be the production lines of N900 for your region is discontinued in favor of newer production, but it may not applicable to other regions.

And it'd not be a bad news if N900 was really discontinued globally, as that means its decendent is ready for production now.
