Remember that Apple's so called amazing design has only really poped up in the last 4 or 5 years. Prior to that they were churning out crap like the original imac, its horrible mouse:

So now the question is, have there been stylish, well designed products before apple and post apple?
I'm pretty sure the answer is yes.
Laptops:
The macbooks were released in 2006. Prior to that, IIRC Apple's laptops consisted of the iBooks (see above).
Here is a sony viao S from 2004:
and a Asus W3v from 2005:
Post apple, we have things like the dell studio xps series:

Phones:
The iphone was released in 2007. Prior to that, we had:
the RAZR from 2004, the nokia 8800 series from 2005 (which I still think is the best looking 'dumbphone' out there):
and of course, the LG KE850 in 2006; commonly called the Prada phone:
Post iPhone, there's really too many to list. We have the original Droid/Milestone, The samsung galaxy S line, and pretty much every phone HTC has made since.
MP3 Players:
The iPod was released 2001. Prior to that we had:
The Rio500 from 1999? i think?:
The Creative Labs Nomad from 1999:
Post iPod we of course have the zune:
and the Sansa players:
So is Apple the only one that has stylish, well designed products? no. Do stylish, well designed products only come out after people copy apple? no.
