If they add-on a software-control option, or an external numeric keypad I'm in. Having come from the Icom R1500 fine-tuning all the time gets tedious while chasing weak signals. Looks nice from ergonomic standpoint, size, et al but something to direct-key enter a frequency - Software or Hardware, would be pretty nice. Radio Reference forums have a running thread on the software updates cleaning up the bugs on it.
I like the size and sound, but for the money, I'd lean toward the R75 for features before I'd lay out that sort of cash.
It may be "software defined" but not software defined in a user-manageable sense. If that comes around, I'd be intrigued by this one.
