We've had this camera for about a week and overall we're very pleased with it. There are no problems connecting it to our iMac using iPhoto (good as there's no software for Macs supplied with the camera) and the pictures it takes are very, VERY good... But... And there's always a but! The menu system is SO frustrating... You'd really have thought that having a touch screen would have meant a simplified menu system which was easy and intuitive to use, but it's really not. Some of the icons are just plain obscure and some of the features seem buried deep within the menu system accessible only after reading through the manual. The touch screen itself isn't particularly good either, you really have to PRESS it to get it to react. It's certainly not able to accept a light touch like my iPhone does, this suggests to me that it'll wear out fairly quickly but obviously as I've only had it a week this is just speculation!
...Yet you'll notice after the above mini-rant I've still awarded four stars. The confusing menu system is only confusing until you've learnt it after then and being a pocket camera, you'll probably never need to go traipsing through it again. After all you're not buying a professional SLR or anything and for a pocket camera it really is fantastic quality much better than my Fujifilm E550.
So all in all, great camera, great looking camera too! But I'd try and use one before you buy it, unless you particularly enjoy reading manuals!
