I was fortunate enough to work in the game industry for a few years (hired to do 'game AI', but also did multiplayer networking, and lots of other fun stuff), working on two Nintendo games, a PC networked hovercraft racing game, and a virtual reality system for Disney. Anyway, I think that Sony has hit it right with the PlayStation Portable: a balance of great style, features, and portability.
I like Sony products because for me they have 'lasting power'. I bought my Sony DSC-F55 digital camera (with audio & video also) 5 years ago, and I still like it. Until it died a tragic death, my Sony Vaio mini-laptop was a prized possession (and my wife also enjoyed it a lot).
I tend to not buy many toys - mostly because I get more pleasure from time with family and friends, and free activities like hiking. However, when I do buy things, I like to buy things with style and quality. Another good example is my Mac iBook: bought it two years ago, and I still get a lot of pleasure from its style and functionality.
Quality over quantity...
