I've been using a Kodak Z650 for some time, and am still very happy with it - does everything you're describing except possibly the wide angle lens (personally I tend to use telephoto more), just about fits in a jacket pocket, and operates readily one-handed.
A quick web search suggests that the nearest equivalent on the market now would be the Kodak Z915, at about £110-£130, with 10x zoom and 10 Mpix, plus basically the same workings.
