The iPad 2 is selling perfectly well at $500. I personally have no use for one, and I somewhat agree that they are just a toy, but obviously there are PLENTY of people willing to pay $500 for it. They're sold out everywhere.
Besides, Apple has absolutely no desire to sell a $300 iPad, nor a $400 tower, nor a $500 laptop. Their whole business model is centered around avoiding the low-end, where profit margins are razor-thin, and where they'd be making lower-quality hardware that lessens their brand reputation. They'd rather leave the "race to the bottom" segment of the market to someone else.
No offense, but for the last decade, the Internet has been abuzz with geeks ranting and raving about everything Apple "should" be doing. Every new product has been crapped on by PC fans, computer geeks, Linux zealots, etc. And you know what? They've been absolutely dead wrong. I wish I had invested my life savings in Apple stock 12 years ago.
