If they labeled an EF-S 15-85mm as 24-136mm, then the f-numbers would have to change too. I don't think you really want that.
What if I was more comfortable with Medium Format, and I ranted that 50mm lenses should be marked 80mm? You'd probably think I was nuts.
Probably.
I'm a bit confused with the f-number bit.
Are you saying that an EF-S lens, lets say a Canon EF-S 17-50 F2.8, at 17mm and f2.8 on a crop sensor camera will meter differently
then a Canon EF 28-70 f2.8, at 28mm and f2.8 on a full framer? (different shutter speed at the same iso)
I didn't know this. (I may have to try this)
I don't think it's a question of what you're comfortable with.
As I said in a early post, 35mm format is more or less the gold standard.
I don't think anyone here would argue this point. (but I may be wrong)
Now that I've HiJacked this thread without really trying, Back to out regular thread.

It will meter the same, but the size of the aperture at 17mm f/2.8 is 6mm. If you labeled the lens 27mm, you couldn't also label it f/2.8 because the size of the aperture is not 27/2.8 (9.6mm).
27mm divided by 6mm gives you 4.5, which is why the DOF of the 17-55 is equivalent to a f/4.5 lens on FF.
I didn't know this. (I may have to try this)
I tried it with my old 5D2 and 7D. They metered nearly the same. They were off by like 1/10 of a second due to the different meters.
As I said in a early post, 35mm format is more or less the gold standard.
In consumer world, yes it is.

An "accurate" reproduction of a scene and a good photograph are often two different things.

A Canon EF 800mm f/5.6 L IS USM weighs 9.9lbs. A gallon of water (or a gallon of milk, etc.) weighs 8.35lbs. Take the gallon of (whatever) and hold it at arms length, like they show in the image. Make a mental note of how it feels in a few seconds.
The description at the link you provided, "I must say this looks like an extremely comfortable setup for general walk around birding.", is almost certainly a joke. (Sarcasm does not translate well to written text. )

I think it would be an easy way to carry around a second body... Just throw it in a pocket and go. I just have a hard time with the $799 price tag. $499ish seems a bit more realistic.
Dont mind:
the limited amount of physical buttons/dials
missing viewfinder
on camera pop-up flash
Like:
Small size
APS-C sized sensor
22mm f/2 kit lens
Adapter for my EF lenses and hotshoe for my Canon flashes.
Love:
Having a small portable camera with 22mm f/2 lens & decent size sensor for street photography or walk around.
Having a small portable video camera that can use my EF lenses with continuous AF.
Throwing it in the bag with my 5d2 & lenses for a backup/2nd body.
Concerns:
speed of AF with M as well as EF lenses
coming up with the $1000 to buy it and the adapter

the price is going to be a sticking point, hope they offer some discounts at year end

I don't see an appropriate level of pain and grimace. (That combination, handheld, would be a physical pain to use.)
