We’ve been waiting in anticipation for this day for quite some time. Apple’s Let’s Rock event has caused so much speculation about what would or would not be talked about that we were seeing the mythical iPod nano 4G in our sleep. But now the time has come and passed and we know what the event brought. And to be honest, this time around, all the speculation was spot on the money.

For starters, iTunes 8.0 was announced and is now available for download. The update is quite significant, adding HD TV shows to their line up for $2.99 each and putting NBC back on board, so your favorite shows like 30 Rock and Heroes can be downloaded once again. 

But most importantly, iTunes received a new feature called Genius, which intelligently creates playlists for you. Remember Pandora Radio? Yeah, it’s sort of like that, but only built right into your iTunes and utilizing your own music. So, when you play a song, a sidebar shows you what goes together with your current selection. And when you buy a song from the iTunes Store, Genius suggests other songs you may like. 

We also found out that all the iPod nano speculation was, indeed, true. In fact, every little detail we heard was confirmed! The nano has gone back to what everyone liked about the second gen nano, that is, the slim form factor. With an aluminum casing and curved glass, this iPod is certainly nice to look at. And it really is thin. An accelerometer is also built in, letting you view cover art in coverflow and watch videos in landscape mode.

It’s available in a variety of colors. So many, Steve calls them “nano-chromatic.” Your options include black, purple, blue, green, yellow, orange, violet, and red. The 8GB is $149 and the 16GB is $199, though you’ll have to wait until next week to buy the latter.

Lastly, the iPod touch got a makeover as well, though it was much less comprehensive. This touch will have a contoured stainless steel body and will be much thinner than the last model. Genius is included as is Nike+. No external dongle is required, either. The receiver is built into the iPod. There was no change in capacity for these devices this time around but they will sell the 8GB for $229, the 16GB for $299 and the $32GB for $399.
