New Slacker Update Introduces Caching to iPhone

Slacker Radio is an extremely popular internet radio app on the iPhone and iPod Touch. It works great for the iPhone, but iPod Touch users get a bit annoyed by it because they can only use it when connected to WiFi, which in my opinion defeats the purpose of having it in the first place. Fortunately at CES 2010 Slacker announced a new update for both devices that will feature caching.
Caching simply means that while connected to the internet, the app loads in tons of new content and keeps ahold of it until you’re ready. Then once it’s used, that content will be refreshed next time you get on the internet. That way, you can listen to it when you don’t have internet access. For instance, anyone that uses an iPhone who flies a lot will love the fact they can use Slacker while in Airplane Mode.
One other benefit: less strain on your iPhone battery. Any improvement in the battery life of the iPhone is welcome!
I’m actually pretty interested in this update. I use Slacker regularly and would like to see this feature integrated. What do you think?
