If you've used one and don't get it, you may not be the target audience. On multiple occasions, I've asked a friend of mine to try various products I use which I believe are excellent in many ways, only to be told that they were average or junk compared to what he uses. I believe what he uses mostly to be complete and utter junk! So I don't know ...
As far as Dyson vacuums go, V10 tipped over for me. The suction improved noticeably as did the run time. The bin is quite larger as well and my pet peeve, emptying the bin cleanly, is done perfectly in V10. I used to have to deal with hair in previous models. After V10, I never once touched the inside of the bin to do extra cleaning.
The motor head in V10 does not get hair in it. It's like magic!
As far as industrial design and feel of it goes, it's a pleasure to hold and use, so much that I sometimes over vacuum.
The warranty and support is the best as usual, even past warranty period.
