I like how the app icons look on the iPhone. Nice, big, and visually vivid, neatly in a row. I'm not much for customization, so the simple yet effective layout of the iPhone app icons are perfect for me. I love the Folders! I find the Android app icons small and with the touted customization, can make the phone look in disarray.
Me too , I don't like the Android GUI . With programmers (The one's I know) they are very good at coding, but not so much with the graphic design. I've only come across a few coders who are great at both. And it's been said that the Android coding community care less about the design of their GUI and more about ease of use, customization , and awesome software features. etc.
A lot of the icons on the Android are just plain and some can be really rasterized to the point where it ruins the experience. Sure the iphone's GUI (Icons etc) on first glance looks like a fisher price toy to some but I love the quality of design, the brightness, the clean finish.
Apple's ecosystem and app store are a breeze, it's just so quick and easy to use.
I have had the HTC Wildfire S for a while (which is now used as an alarm clock) just to see what it was like, it's cheap, it feels cheap, looks cheap. However! the Samsung Galaxy 3 does look like an awesome handset, it's just not for me. If there's one thing I love about Android it's the customization, open source etc.
I love the design of the iphone, it's superb, nothing comes close to it in terms of the Software, Hardware, design and quality of both.
