idle thoughts

If you have a perfectly good Tamron 17-35, Tamron 28-75 and Tamron 70-300 and saw the Canon 17-55 f2.8L IS and Canon 70-300 f4L IS how inclined would you be to sell your Tamrons and go for the Canons?

i would not have bought the Tamron in the first place
I did tick Im a gear head Not that i have more money than sence But i will buy what give's me the best chance of getting the shot IS will give me that chance.
EDDIT
if Nikon were to sudenly bring out a far better system than Canon that hit spot on focus 90% of the time on birds in flight then i would change over to them .

The efs 17-55 IS and the 70-200 IS make a great pair.

They make a fantastic pair. If they had been around when I bought my Tamrons then I probably would have bought them instead of the Tamrons. Having had IS on my Canon S1 IS and having tested it with IS on and off, I am pretty sold on IS. I have no problem using non-IS lenses but this is one area where modern technology really helps and where it reduces my need to carry a tripod.

I can't see my selling my Tamrons at the moment as they're pretty good lenses. Maybe sometime in the future I will but it's not a priority - well - until I get enough income to be able to do so.

Difficult one - I don't own and have never owned a Tamron lens - But I do have the Canon 24-105L and the IS on this lens has come in really handy - so knowing what I know now and as a general question, Yes I would be 'Very Inclined'.

I'd like to see IS on a wider lens for example a nice 12-24 IS.

There's no real point. IS is there to counteract the camera shake on decent length zooms. Camera shake problems at wide angles won't be as prevalent, so there's no real need for IS.

On cropped cameras such as the XT a 12mm lens would be the equivalent of 19mm. It's always possible to view camera shake - no matter what the focal length.
