I have been contemplating getting an iPad for a while and thought I would get the mini but having released the specs, I will pass on it. After a little thought I am thinking about getting the iPad 4 but having never been to an apple store on release day I am unsure whether to go to one or just order online and wait the estimated 2 weeks for delivery (I only want a wifi version). So the question is, how busy are the stores in the UK on iPad release day (will probably be at the trafford center) and how long does the stock usually last on a release day?
