One thing that I was impressed is the brake mechanism.It is nice to see and to touch,easy to use,dismantle and re-install.This reminds me of the design of iPod-nice to eyes,good feeling to the touch and very easy to operate.I don't need to be a computer hacker to add songs and play the music!
I am no expert to elaborate the good design criteria, but I observe that simplicity is the key denominator to the successful sales of consumer products.
Another product that I love to use is moleskine notebook.It is a very useful and felxible analogue "PDA" for me.No virus can create havoc inside it and it never runs out of battery.( except when all the pages are fully written).Anothet reason why I use moleskine notebook is because it makes me write and it keeps me writing...
Can you share with us your personal experience in using products that have 'simplicity' built-in their designs? Thank you.
