Sony DSC-W55

I read comments about it having blurry pictures because it didn't have the image stabilizer option, but is that option THAT important? I mean, will all of my pictures come out blurry?
I also saw a lot of positive feedback for Canon PowerShot A570 IS but it's a bit bulky... and not very attractive, although it has more features and is cheaper.

Which one would you guys pick? Do you guys have any other recommendations?
Thanks for your input!
