Just discovered (The hard way) that, while it's OK to use a single instance of iTunes for both an iPhone and an iPad, it has one drawback. iTunes does a good job of keeping the devices independant of each other for pretty much everything.....except music! I've had iPhones from day one but took the plunge and bought a 64GB WiFi+3G iPad (Sold my Motorola Xoom on ebay today!). ...that was a crap device. You can only have one common set of music sync'd to all devices.... which I now realise sucks because I have a 16BG iPhone and a 64GB iPad. This means it is governed by the lowest denominator being the iPhone. I can only have 13GB of music (actual storage available on the iPhone) on the iPad. can anyone confim this to be the case?
