Flexible funding = probably a scam. It looks like you have actual hardware, but flex-funding is going to scare away the great majority of possible backers, with good reason. Fixed funding is the ONLY acceptable option for a serious project.
Why do you have a XBox 360 logo? Unless your dongle will work with xbox controllers (which are not bluetooth*), you should probably remove it. Furthermore, later on you say "Xbox360 - not supported at all.". Wat. Why the hell do you have the xbox logo then?
From what I can glean, you're basically enumerating as a mouse/keyboard, and translating bluetooth HID device commands to plain old mouse/keyboard commands on the fly? You need to make it MUCH more clear that this is for bluetooth devices only. Frankly, the whole pitch is kinda incoherent, and doesn't really tell me what the thing you're trying to sell actually does.
You pitch here "USB over Bluetooth for Android" also has NOTHING to do with what your hardware actually does. "USB over Bluetooth" means you're sending USB over bluetooth. What you are actually doing is transmitting HID events (?)/ key-events over bluetooth, and just enumerating as a USB HID at one end. Unless you're piping the complete USB connection over bluetooth (THAT would be cool), don't call it that.
And the most major complaint:
Why the FUCK would I want to use a smart-phone as remote mouse/keyboard for a PC? The touch-screen UI is HORRIBLE! I mean, it's as good as it can get for a non-tactile feedback device of it's size, but if I'm close enough to connect using bluetooth, I'm close enough to use a proper keyboard.
It seems like you've basically make a very complex bluetooth wireless presenter, with all the commensurate limitations.

I'd probably think this was a lot more cool if it could translate between some of the obnoxious complex proprietary bluetooth game-pads and a computer without needing a custom bluetooth stack. If you make it enumerate a bluetooth PS3 game-pad as a plain old HID/driver-install-free gamepad with good enough latency, I might buy one.
