With all the fanfare this week surrounding the iPhone, let's not forget the famed handset's red-headed stepchild: the iPod touch.

Hardware updates to the line weren't exactly expected just now. Apple tends to save their iPod updates for special music events held every year since 2003. After Apple's education promo is done and dusted, we can probably expect a special event in September where we see updates for our favorite media device. What's in store for the new iPod touch? Setting aside for the moment rumors about a tablet-sized device, there are sure to be plenty of updates for the handheld iPod touch we've come to know and love.

As far as the operating system update is concerned, we'll gain all the features compatible with the iPod touch's hardware, like copy and paste, upgrades to the iTunes store, and the landscape keyboard. These updates, like those in the past, will come at a price: In an effort to adhere to strict accounting regulations, Apple charges iPod touch users about $10 to upgrade to the new operating system. iPhone users aren't charged similarly, because revenue from the handsets is accounted on a subscription basis, which has different rules about giving updates away for free. Like the iPhone, the update for iPod touch will be available June 17.

Compared to the iPhone, planned updates to the iPod touch's hardware remain largely unknown. iPod touch models have been generally close in specification to the iPhone, but each model is slightly different. In theory, if applications require the greater horsepower the iPhone 3G S provides, some high-performance games may be incompatible with existing iPod touch models, in addition to apps that take advantage of the iPhone's built-in GPS and camera.

Cameras, however, might be on the way: Mike noted rumors last month about iPod nanos with cameras built-in. If those are true, it stands to reason that iPod touch models could get the same functionality. I've opined before about a whispernet service for the iPod touch, but I don't see that happening anytime soon, especially with AT&T's lackluster feature delivery schedule revealed during the iPhone keynote.

What do you think the next iPod touch will be? Will it become "just like the iPhone but without the phone part?" Let us know by leaving a comment.

Don't get me wrong, I love my iPod touch. As a matter of fact, I'm writing this post with it on the beach as my girlfriend goes surfing. But with Apple's new product announcement on Tuesday, it makes me wonder what changes could be in store for our favorite supercharged music player.

I think the single greatest thing Apple could do for the iPod touch is take a page from the Amazon Kindle and offer free "Whispernet" service for every iPod touch sold. (Or, say, roll it in with a Mobile Me subscription.) Amazon bought access to a chunk of Sprint's EVDO network, which means every Kindle has network access wherever it goes.

Apple could make such a deal with AT&T -- and its various partners worldwide -- to provide the necessary bandwidth. Who knows -- perhaps they have already. Allow tethering with software like NetShare, and you've got Internet access for your Mac, too. Instant-on, and always there. Brilliant.

Another simple addition would be GPS functionality, bringing the iPod touch in line with its newer sibling. Suddenly, the need for both a GPS and an iPod in your car is obviated, and it opens up interesting opportunities with the car manufacturers who already offer iPod integration in their vehicles.

Third, and this could apply to new iPhones too, would be to allow access to the dock connector for Apps. This opens up all kinds of options for iPhone and iPod touch owners to use voice recorders and cameras, as well as potentially control a wide range of equipment from industrial automation tools to backyard telescopes.

Who knows what Apple has up their sleeve? Certainly not me. But with this wish list fulfilled, you can be sure a new iPod touch is in my immediate future.
