Found in the internet:
If IBM made toasters… They would want one big toaster where people bring bread to be submitted for overnight toasting. IBM would claim a worldwide market for five, maybe six toasters.
If Microsoft made toasters… Every time you bought a loaf of bread, you would have to buy a toaster. You wouldn’t have to take the toaster, but you’d still have to pay for it anyway. Toaster ‘2000 would weigh 15000 pounds (hence requiring a reinforced steel countertop), draw enough electricity to power a small city, take up 95% of the space in your kitchen, would claim to be the first toaster that lets you control how light or dark you want your toast to be, and would secretly interrogate your other appliances to find out who made them. Everyone would hate Microsoft toasters, but nonetheless would buy them since most of the good bread only works with their toasters.
If Apple made toasters… It would do everything the Microsoft toaster does, but five years earlier. The toast would make a little smiley face at you when it popped up, or else it would get stuck and there would be a little picture of a bomb burned onto it. If they break, these toasters would require a special set of MacToaster Tools to even open up. Worldwide market share would only be 5%, but all the bread in school lunches would be exclusively toasted on the MacToaster.
If Sony made toasters… Their Sony Toastman, which would be barely larger than the single piece of bread it is meant to toast, can be conveniently attached to your belt.
If Xerox made toasters… You could toast one-sided or two-sided. Successive slices would get lighter and lighter. The toaster would jam your bread for you.
If Radio Shack made toasters… The staff would sell you a toaster, but not know anything about it, and you’d have to buy 4 or 5 before finding one that works right out of the box. Or you could buy all the parts to build your own toaster.
If Oracle made toasters… They would claim their toaster was compatible with all brands and styles of bread, but when you got it home you’d discover the Bagel Engine was still in development, the Croissant extension was three years away, and that indeed the whole appliance was good at blowing smoke.
If Unix made toasters… Very few people would understand how to make toast. There would be toaster geeks, in pony tails, jeans and tee-shirts who would spend sixteen hours a day in front of the toaster making toast.
