I just read a story about a new Google tool that looks like it's going to lead to loads more apps for us. App Inventor lets you create apps without having to know any code at all. On the downside we're probably going to see a bunch more crappy apps, but it'll let us create our own too. I don't know about you, but I'm definitely going to be playing around with this! Looks like you need to sign up for access, but hopefully it won't be too hard to get it.
