You also need to consider that the OS X on the iPhone only needs to support one processor and those components right now. Build new ones with updated processors and it'll get larger...

OSX.4 itself is only around 3 gigs. Not suprising.

Pretty sweet deal. They optimized it specifically for the phone, which is to be expected, but from what he was showing, it was very very strong for only being 1/2 a gig.

I agree about the flash memory, didn't think of it initially but imagine how much abuse phones can take. Flash certainly wouldn't hurt.

I thought this comment from Samsung was interesting, when asked about the device:

Chu Woo-sik, senior vice president and head of Samsung's investor-relations team, was optimistic about the iPhone's potential impact, but refused to offer details about what it could mean for Samsung in terms of supplying components like NAND chips.

"It seems iPhone will be using the whole spectrum of memory chips,"

I wonder what processor Apple is using for the iPhone. Hopefully its kilocore: http://www.kilocore.com/ if not they would need to recompile OS X to run on an ARM based CPU

Apple engineers did a great job, especially if that "considerably less than half a GB" is correct and not just 500 MB

While I think it's great that they put OS X onto 500MB of flash memory, it's somewhat wasted if Apple's the only company making apps for the iPhone OS X platform.

Instead of having the current 10,000+ Mac OS X applications that could be converted and run on the iPhone, they're starting at the dozen or so apps they've put on already. Really doesn't make sense to limit this new platform unless they had to really tweek things to get good performance/stability out of it.

After all, OS X does have memory protection and a lot of proven stability to be that worried that it might crash the phone portion.

You just have to keep the core OS and Apple apps separate from the user apps and have a 'safe mode' that allows for emergency use of the phone if a user app crashes the phone.

Just have all apps and widgets and library items install in the 'User' portion and don't allow admin access to the core OS unless its docked with a Mac/pc for updating.

For crist's sake, I can download 3rd party apps for my many years old and crappy SonyErricson T610 phone... not beiing able to do that on a $600 phone? Not a good thing.

Hopefully by the developer's conference in June, Apple will decide to open it up more. Since the phone will start to be available then, it's a perfect chance to do it.

Thought as much. I'm pretty sure they are using the same design as Windows Mobile in how they handle the OS. There is a segment cut off for the OS to run Apps and the OS...this in its traditional sense is RAM. Then a segment for the OS's files which would be considered the hard drive in a desktop environment. I'm pretty sure they are probably using up about 1GB+ of storage on flash that is isolated from the storage area that will hold music/movies/etc which you simply don't see.

I think there is now even less reason for Apple to be limiting 3rd party support because it sounds as if they have left plenty of room for expansion with such a setup. :(
