Say you have a div with an id of "#footer" that you want to stay at the bottom of the page. If you set it's position to "fixed" and set the bottom to "0px". When viewed on an iPad, iPhone or iPod Touch, the footer may end up in the middle of your content if you have a long page.

I say this because it seems to be the way the Apple software ecosystem works. There are a few applications, written by developers who have been working on the Apple platform for a great number of years, that are constantly recommended and very successful.

1. It requires XCode.  - I’m not sure if they can get around this one. It seems like they should be able to. All XCode does is call GCC and compile the code. My guess is that it has to do with the licensing of the iPhone SDK and/or the iPhone libraries that you can’t distribute. If you could bundle the iPhone headers, it seems to me that you could compile an iPhone app on any platform that supports GCC. DOH! As Miguel reminds me in the comments, it doesn't use XCode but the iPhone simulator is only available on Intel Macs. (1)
2. It costs 400 frickin’ dollars. – So now, not only do you have to buy a Mac, pay Apple $99 per year to get in the App store (which is no guarantee) but if you want to use MonoTouch you have to pay $399 U.S.

So what you have to ask your self is: Is learning Objective-C something that I really can’t/won’t do to become an iPhone developer?

There are a lot of benefits to developing for the iPhone using MonoTouch. Access to most of the .NET library. LINQ is available, WCF. Miguel DeIcaza has a good explanation for why Monotouch costs $400, which he'll talk about in an upcoming episode of Herding Code. But I think that the price is going to really slow MonoTouch adoption.

(1) That's what I get for writing a blog post ahead of time and not reviewing it before it's scheduled to post.

I've had Safari 3 for Windows installed for quite a while at work as a test platform. Occasionally, until I told Apple Software Update to shut up, it would prompt me to install iTunes + QuickTime since I didn't have it installed. So it's not that Apple is pushing Safari specifically through Apple Software Update, it's pushing Apple Software period. Which seems to be the same thing as Windows Update. I don't see it as particularly aggressive. The Google Pack updater will suggest other items that you haven't installed yet. It just seems to be the way smart software updaters work.

Shelley Powers asked us for some other artist branded iPods. I came up with a few.

A Dolly Parton iPod with HUGE headphones and a rhinestone click wheel?

A Van Halen model except the hard drive and head phones won't work with the iPod and come separately.

A Cat Stevens model - works beautifully for 3 years, then quits. Finds religion.

non-musical
A Transformer iPod - Transforms into a Zune. Obviously a Decepticon.

Let's count up where Safari/WebKit is in use as of today.

Adobe AIR uses WebKit as their HTML/Javascript engine.

Safari runs under both OS X 10.4.9 Tiger and 10.5 Leopard and Windows XP/Vista.

Safari runs on the iPhone.

My gut tells me that Safari on Windows combined with AIR using WebKit AND third-party development on the iPhone being done against Safari is going to be much, much more significant than we realize right now.

Depending on the adoption of the iPhone and AIR, the browser war could turn into IE vs. Safari instead of IE vs. FireFox like everyone expected.

So, can I access it under Windows? Without resorting to sharing it as a network share?

It's 2007, I'm really looking for a filesystem I can format my external USB hard drives with, that doesn't suck, that I can access from either my Windows or Apple computers. Fat32 is what? 10 years old now? When was Win95 OSR2 released? It's time for a new system. Hopefully someone will release ZFS drivers for Windows.

There are two different Silverlight sites. microsoft.com/silverlight and the community site at silverlight.net.

You can't get to the system requirements for Silverlight through the community site (in fact, there is a link called "system requirements" on that page, but nothing seems to be clickable for me right now). If you click on "getting Started" at the community site and click on the links to download the specific version for your platform, the system requirements only state "OS X 10.4+". You can only get to them by going to the main microsoft.com/silverlight downloads page. There I found the system requirements

for 1.0

System Requirements: Macintosh Computer with Power PC Processor

* Supported operating systems: Apple Mac OS X
* Supported browsers: Firefox 1.5.0.8, Firefox 2.0.x, and Apple Safari 2.0.4
* Minimum recommended hardware: Power PC G3 500-megahertz (MHz) or faster processor

System Requirements: Macintosh Computer with Intel Processor

* Supported operating systems: Apple Mac OS X
* Supported browsers: Firefox 1.5.0.8, Firefox 2.0.x, and Apple Safari 2.0.4
* Minimum recommended hardware: Intel Core Duo 1.83-gigahertz (GHz) or faster processor
128 megabytes (MB) of RAM

for 1.1

System Requirements: Macintosh Computer with Intel Processor

* Supported operating systems: Apple Mac OS X
* Supported browsers: Firefox 1.5.0.8, Firefox 2.0.x, and Apple Safari 2.0.4
* Minimum recommended hardware: Intel Core Duo 1.83-gigahertz (GHz) or faster processor
128 megabytes (MB) of RAM

It's a not so subtle difference. It's something to keep in mind if you are a PowerPC owner and want to play with Silverlight. You're stuck with version 1.0. No Dynamic CLR for you! It'd be nice if a MS employee would post a notice about future PPC support for Silverlight?
