iPhone SDK in February!

You can perfectly make games in Javascript that are both fun and visually appealing. Don't worry about the speed. Safari's Javascript is one of the best I've seen, and I speak from experience.
I think you *should* worry about the speed:

Code:
Let’s run some benchmarks comparing the iPhone to my iMac running Safari 3 on a 1.83 Ghz Intel Core Duo processor:
Test iMac iPhone Slower by
100,000 iterations 0.041 secs. 3.209 secs. 78x
10,000 divisions 0.005 0.413 82x
10,000 sin(x) calls 0.009 0.709 79x
10,000 string allocations 0.010 0.777 78x
10,000 function calls 0.010 0.904 90xAnd...
Code:
Let’s see how Javascript compares to native code running on the iPhone:
Test Native Javascript Slower by
100,000 iterations 0.015 secs. 3.209 secs. 214x
10,000 divisions 0.004 0.413 103x
10,000 sin(x) calls 0.105 0.709 7x
10,000 string allocations 0.085 0.777 9x
10,000 function calls 0.004 0.904 226x

Let's stay focused here OK. Ofcourse making a game that uses a lot of math, and especially sin and cos functions, will be slower in Javascript than on any other language.
Javascript is not the solution for that. Instead of thinking of making a DOOM game for the iPhone, concentrate on a simple game like Tic-Tac-Toe or even a Tetris clone would do.
Strange that the guy who did the benchmarks didn't mention the connection speed.
At work I tested the iPod Touch on a website that heavily uses JavaScript (my own scripts) and it worked acceptable using a WiFi (ADSL) connection. Lots of Ajax and lots of playing with the DOM and doing effects like fades etc..
Ofcourse a desktop computer will outperform an iPhone, but that's not the point. Even if somehow Apple decided to make the SDK C based with OpenGL support, it will still be slower than the desktop.

Wait, this doesn't look so good anymore - the only thing we're going to be allowed to run on an iPhone is Widgets ? And without flash too you say ? 
Puh. My excitement now seems misplaced - we aren't going to be getting our native 3D games on iPhone 
I guess it was quite fanciful to think that it would be allowed..?

Well, this email from ADC, "Introducing the iPhone Dev Center". It says "..your single source for information on desiging, coding and optimizing web applications for iPhone and iPod touch."
Then there are sections like "Web development guidelines", "Safari Compatibility" and "Web App Submission".
This leads me to assume it means Widgets only

I'm thinking the current iPhone dev center has little or nothing to do with the SDK that's being released in February. It's just an expansion of what they already had for developing web applications for the iPhone.
...but then, I'm an optimist, so who knows.
