3.0.2 to 3.0.4 is not a big update. It's actually quite minor. And there are grumblings of the WebOS team disbanding. WebOS's best days are likely behind it -which is unfortunate because I purchased a TouchPad through the firesale and quite like it.

Read "Guns, Germs, and Steel" by Jared Diamond. He very clearly outlines why development was accelerated in some regions and not others.

HikingStick is exactly right. We used Hummingbird for a while and it got out of hand and then it was every bit as bad as what you're experiencing now but we paid an arm and a leg for it (so it felt much worse). It's a decent product, but we ended up with migrating to SharePoint since it fit our needs.

Completely different. In the case of playing real guitar, the unamplified string sounds you are playing are on pitch with whatever is coming from the amplifier. When using a real guitar as a game controller, the actual frequency that the string rings at will clash with the sound that emanates from the TV.

The problem I see with it is that unless you turn your TV's sound way up, you're going to hear the tinny off-key strings of the guitar while you play. It'll just be random notes (chromatic scales on a lot of the runs) that will be very off-putting beyond the first few minutes. I appreciate the feel of a real guitar, but the Guitar Hero controllers feel just about perfect for what they're asked to do.
