It's truly bizarre to me that almost 20 years after Canon's first IS lens people still insist on staying ignorant about the benefits of IS. IS is not just about counteracting shaky hands, IS allows you to shoot at lower shutter speeds than you normally would. f/4.5 with 3-4 stops optical stabilization on this lens will be able to handle lower shutter speeds than f/3.5 without on the 10-22mm. Can you use your imagination to think of any scenarios where lower shutter speeds are indispensable?
I can successively shoot an EF 85mm f/1.8 at 1/4 second on a crop-camera. Therefore the EF-S 10-22mm f/3.5-4.5 is not a problem,
for me. YMMV. I can also drive a stick-shift (manual) transmission car. YMMV.
There are many times an IS system is handy -- Long Whites comes to mind.
But a 10-18mm you've to to be kidding!
But not-to-worry, your side has won :

Canon has also added Image Stabilization to the EF 16-35mmf/4L IS USM. When will Canon add IS to the EF 14mm f/2.8L and EF 15mm f/2.8L ??? I'm sure that Zeiss will soon add IS to their Wide Angle Prime lenses
I have been shooting photos for years, and was very happy when image stabilisation / optical stabilisation came out. It definitely benefit many of my photo opportunities (both in lenses, and in digital P&S’s).
Some people definitely have steadier hands than others (and some people are better practised at this). However to suggest that most people could consistently achieve sharp hand held photos with exposure of 1/4 second at 85mm (on an APS-C body) is a fallacy. I would suggest that even the steadiest percentile of photographers can not achieve this
consistently!
Much of my photography requires small apertures… eg f/8 to f/16 (yes, I know… diffraction starts to set in… but this overall very minor decrease in sharpness (ie at small apertures like f/16) is offset by having a photo with a sufficiently sharp (close) foreground to (distant) background.
There is definitely a place for IS, also in UWAs. In fact for several years, I have been hoping that Canon might even come out with an in-body IS system. Yes, I’ll admit it – I’m jealous of that possibility offered by some other manufacturers.
On the whole I prefer the overall Canon system (features and quality of DSLR bodies, lenses and accessories). Even if in body IS offered 2 to 3 stops of IS (rather than the 4 in most new lenses) that would be welcome… I fully realise I’m being quite hopeful and optimistic in this, but an extra 2 to 3 stops stabilisation for my Sigma 8-16 would be AWESOME. (It’s such a good lens!) I’m thrilled with my Canon 15-85mm as my walk around, it’s 4 stop effective IS proves so useful – also at 15mm.
Sure I find most use for IS on my fantastic 70-300mm L, where that lens' 4 stop IS is really helpful, and in some ways a 'photo saver'.
But even then, for many of my photos, a steady tripod is required. There is nothing like having a good sturdy tripod from which to take photos with any duration of shutter speed. Just IS is helpful for when I don’t want to lug around a tripod (or when they are not allowed in certain environments).
Professional photographers and videographers alike use IS extensively – AND use tripods too. That’s not to say that in all situations tripods are required, or that photographers who don’t have or use a tripod – are ‘unprofessional’ or ‘limited’. They might just not do that type of photography that requires it… OR they might be happy with ‘blurry photos’ (and I’m not talking about pixel peeping… I’m not a pixel peeper!) To suggest that either IS and/or tripods are not needed shows an ignorance about the breadth and requirements within certain genres of photography.
Well done Canon for introducing IS into your first UWA – in the EF-M 11-22mm. And thanks now for adding IS to the EF 16-35mm L F/4 and the EF-S 10-18mm. It’s a good thing!
