I have a similar combination, the i7 with a 240, and I also think they're great. I can't even remember life before daily automatic floor cleanings. I think you're right about iRobot's competition iterating more quickly, and I'm also concerned that they might get left behind. Another concern is their pricing. They're clearing trying to establish their robots as the premium models in the market space—ones that "just work"—but the price tags are astronomical. Their two flagship models, which were advertised as working best in tandem, cost nearly $2,000 together when they were first released.

Yes -- pricing. Just for reference, the i7+ costs 140.000 yen here in Japan, that's $1300 USD, while the competition costs the same as everywhere else. In the US the same product costs $700 and often has some discounts available. (I just imported mine because I ain't gonna pay that much). It's also currently 'sold out' on their JP online store.
