I think you mistyped - should have been "and entirely not open source".

iPhone and Nokia ITs are entirely different beers - iPhone is a commercial phone with commercial oriented applications and no SDK from Apple is going to change that for a company that charges 20$ for the iPod Touch mail app. Why do you think Apple is going to have a change of heart and become entirely open? You don't have a problem with 100$ for a SDK from them, but you have a problem with entirely free one for Maemo, maybe because it doesn't install you a dazzling IDE and doesn't convert your old Linux PC to a Leopard (or was it the other way round? oh, nevermind)?

The goal of Apple is simple and many before them have done it - charge for the development tools, offer a free beer, promise millions of eventual customers, then leave the developer write open source/free... or will he?

Oh, just read that...
• Free through Apple Developer Connection?
Not exactly - It's a free beta for anyone, but Apple launched the iPhone Developer Program which will charge developers $99 per year for the right to publicly release iPhone apps, and distribute them via the new App Store.

One time fee from Apple? Naa...
