Ixus offers bang per buck; unless you’re going to start fettling, in which case buy a DSLR!
A lot of compacts are very good now, but a lot are not. If you want point and shoot then go canon IMO.
Panasonic, sorry, Lumix are ok but have falings as mentioned previously.
If you think your camera phone takes good pics then I’d advise you stick with that, because it’s ISO, white balance, quality auto settings etc that comes into play with compact cameras and you’d be as well spending £100 on a good modern compact which will provide noticable differences over your phone, rather that over twice as much in a Canon S100, for which (and only judging by your original posting)..you won’t notice much difference!
One thing I would say irrespective on my views on manufacturer, is IGNORE megapixels, unless you’re planning on printing A3+ pictures.
