If the connection has changed, it will be for a legitimate reason—in this case so you can release the cleaner head without bending down, which is a great idea I wasn't expecting. Wonder how many will dupe that the first chance they get. Unless Dyson drop the ball again with their flavour offerings, it would make sense that all tools would come with the machine such that the change in connection was irrelevant. They've already upgraded the hair screw tool and it looks from their gallery that they supply their other tools with it, with some upgraded.
What amazes me from reactions I've seen on the internet is how cosmetics matter more than substance and innovation. Frightening. Many of the amazing and pioneering features of this machine and why they're useful for the chore of cleaning, have gone completely unnoticed. Dyson's marketing doesn't really go into it either, if at all in some cases. Maybe they presumed it's too deep for the lay audience. It's called 'piston' for reasons more than the cleankompactor feature. Bit sad really. I suspect a detailed discussion of them and the associated science will only be found in my eventual review.
I bet it costs less than the Samsung Bespoke Jet and Vorwerk cordless offerings (~£1200) but will still be regarded as 'overpriced', whilst those other two machines get a free pass. The Won to £ conversion looks to be about £750-800, but there'll be a rip-off factor added, I suspect.
