If I wanted an XL, I would've gotten an XL.
That said, I'm still kinda put off by the "no upgrades" thing given that support for backwards compatibility is said to be the driver for the decision. It seems rather unlike Cliff to paint himself into a corner, increasing the FW image size to the point that the Mk 1 hardware can't support it. I wouldn't go so far as to say that it's planned obsolescence but the decision not to make the compatibility modes conditional when they were implemented is a heckuva case of unplanned obsolescence.
