Electronics is probably man's greatest weakness. Perhaps fast cars or sporting memorabilia could be up there too, but electronics appeal to such a broad audience in a numbers of areas that it is hard to compete with.
If you walk into the large retailers, you will see tons of the 18 to 30 crowd. Lots of disposable income and a hunger for digital entertainment. Bigger is better. Faster is better. Higher quality is better. You can always upgrade.
I love walking into an electronics store and checking things out. It is like clothes shopping for women.
