Apple designs great interfaces. I accepted the interface of 'smartphones' as an unpleasant necessity until the first time I tried an Iphone. The interface design was a spectacular improvement, on the scale of going from a bicycle to an automobile for transportation.
While I didn't buy an Iphone as I don't care for the rest of the Apple package, their products are mostly the pinnacle of interface quality. I do own an Ipod, although not until I had software that allowed me to really own it.
I think Apple's reputation for interface design is overhyped. iTunes is a bit of a nightmare. The last iPod I owned was also annoying to use (first one with click wheel).
