I'm gonna go and hug him now haha
...am I reading that part right, or have I just been on the wine a bit too much tonight? 
Marcus, let me get one thing perfectly clear. I don't have anything against your DC41.2. At all. I'm really glad that you've found a product that works so well for you. I've not had chance to use the mk2 yet, so I can't comment. But overall, I'm not a fan of Dyson products (any of them!), I don't like James Dyson as a person based on what I know and I don't like the company. Whilst I've no major issue with the performance of their cleaners, I've always found them very mediocre for the price you pay. I don't think that the high price tag reflects the quality of the machine you get.
But, as I said, it's great that you're happy with your Dyson. I'm interested in all sorts of vacuums - upright, cylinder, handheld, bagged, bagless, wet filter etc. I wouldn't necessarily want to use a bagless vacuum in my home all the time, but it doesn't mean I don't appreciate them or find them interesting.
Now, as Matt said, this isn't a brand-bashing thread. But I just wanted to make it clear that my issue is not with your choice of vacuum AT ALL.
