Just joined - I've used an iPod Touch for over a year & now have an iPhone 4; both running iOS5. Have used Macs without a break since 1990, but also have a PC laptop, which I use for music editing. Not an expert in iOS, but looking forward to learning more & passing on anything I've picked up so far. I'm enjoying the music & recording apps available for my iPhone & will be exploring them in more detail - amazing that such a small device can do so much..
