Let me declare up front that I am not an Apple Mac user. My pc of preference is Sony.
I bought my second iPod at the weekend. The old 40GB unit us a bit bulky so I went for a shuffle. The experience is what I aspire to for clients of my software company. Easy to install and a pleasure to use. 10 out of 10.
Okay, so point of sale software is a tad more complex than a music player. However, Apple teaches us something about elegance of design, simplicity of use and missionary like focus on the goals of the product. I certainly found it motivating from the perspective of software development and a commitment to focusing on customer outcomes.
