I think that I will buy a PlayStation Portable (when available in the US)
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...
