Apple Thoughts: Multifl0w Multitasking Implementation on Jailbroken iOS Devices

"Multifl0w is how we feel Apple should have implemented multitasking into iOS in the first place. It works quickly, beautifully, and efficiently on jailbroken iPhones, iPod touches and... iPads!"

If you've jailbroken your iPhone, iPod Touch or iPad, then this looks pretty cool. I think multitasking works well enough in iOS 4, but this does look a little more elegant, at least when it comes to task switching. I'd be curious to find out, though, if it reduces battery life. The app costs $4.99 in the Cydia store. If you've used it, what has your experience been like? As I said earlier, I'm very curious about how it affects battery life.
