I'm considering doing the same thing. Managed to borrow the Canon and the Fuji superzoom, and am currently leaning towards the Fuji - and I will probably be buying. I see it being useful in some roles.
I'm not a pro. Strictly sub-amateur - but I do know the ins and outs of course and I do know what I find usable.
One thing's for sure with these things - the images are *definitely* from a compact camera either way. There is no way you'd mistake the output as coming from an APS-C class sensor, even in an unfair crop test heavily favouring the superzoom.
30-35x zoom is, frankly, ridiculous. What is amazing though is that it's actually quite usable (especially on the Fuji for various reasons, including the lens).
Throckmorton has a good point, but better glass has merits in terms of frequent use of long zoom - there is definitely more capability on hand than a travelzoom. The demerit is that although it is smaller than a DSLR and obviously taking 2-3 lenses with you, it is marhuuursssive ("massive" doesn't really do the disparity justice) compared to a really compact compact like the S95.
If you're not planning to explore the outer edges of the focal length options, then something like a NEX would make much more sense (although of course it'd cost more) and would be much smaller with the short zoom - and the combo will throw out *much* better pictures within the limits of the focal length, and even further out to a degree if you consider the crop limitations of the compact camera sensor vs APS-C.
Personally I have the older NEX-5 and I still find the Canon/Fuji would make sense to buy for a number of reasons. The zoom option is obvious but the fact that it's basically an all-in-one box - especially the Fuji, in terms of the lens performance, exposure options and aperture options at short zoom ranges combined with the long reach, the shoot-properly-anywhere versatility with the tilting/swivelling (Fuji/Canon) display + the EVF, and the much-better-than-compact-compact video capability - does give it a place in situations I don't want to be fumbling around with the Sony and a couple of lenses. It's all there, and the speed from which I can go from shooting something hundreds of meters away to shooting something right in front of my face, especially with the Fuji, is almost supernatural.
It's just that your usage vector has to justify it because of the size/IQ compromise, and for some people a DSLR + mirrorless, or a combo of DSLR + ultracompact, might make more sense. Rather like a laptop, if you buy it on the basis of 'I think I might need to do everything, so I'll get something cheap that does everything' may mean you end up shooting youself in the foot if e.g. all you really actually need is something in the 20-80mm range like most people.
Ultimately it's an odd halfway house really - it's nowhere near a half-decent DSLR/mirrorless IQ wise while being almost as large, yet it provides much more shooting options and opportunity than anything actually compact. I think though coming from a DSLR as opposed to going up from a compact, the limitations of the sensor may bother you more, though it will be less of an issue if you learn to shoot to the camera's strengths.
